SUMMARY:Speaker: Samuel Hinton - University of Queensland
DESCRIPTION:Title:  Challenges and pathways forward in supernova cosmology \nAbstract:  Using the DES photometric supernova cosmology analysis as groundwork\, I will summarise our current analysis methodologies\, from simulations\, to transient classification\, selection effect treatment\, and cosmology. Despite recent improvements in analysis methods\, there still exist fundamental challenges in areas spanning the initial empirical SN Ia model all the way to failing approximations built into cosmology fitters. I will highlight potential solutions to these challenges\, to allow the next generation of surveys to lower the systematic floor and provide improved cosmological constraints. Additionally\, I will also summarise my BAO and pipeline work for surveys like DESI\, and discuss ways I’ve improved scientific workflow to allow more efficient use of researcher time.

SUMMARY:Speaker: Arnaud De Mattia - IRFU\, CEA\, Université Paris-Saclay
DESCRIPTION:Title: The extended Baryon Oscillation Spectroscopic Survey: clustering measurements\, lessons\, and prospects \nAbstract: In this talk\, I will present the clustering analysis of the ELG (Emission Line Galaxy) sample from the eBOSS (extended Baryon Oscillation Spectroscopic Survey) program of the Sloan Digital Sky Survey and review the other clustering analyses of the eBOSS program\, dedicated to Luminous Red Galaxies and Quasars. I will discuss theoretical\, observational and analysis systematics\, how they were estimated and mitigated\, focusing on the improvements over the last release of the BOSS program in 2016. Specifically\, I will start by presenting the extensive work of the eBOSS collaboration to test model predictions against N-body simulations. The different observational systematics of the eBOSS samples will be reviewed\, as well as the adopted correction schemes and the new analysis techniques used to mitigate residual systematics. Different analysis assumptions and their impact on the clustering signal will be discussed. After a review of eBOSS legacy cosmological measurements\, I will finish by drawing lessons and prospects for future galaxy surveys.

SUMMARY:Speaker: Jiamin Hou - Max-Planck - Institute for Extraterrestrial Physics
DESCRIPTION:Title: Clustering measurements in the final eBOSS quasar sample and their cosmological implications \nAbstract:In this talk I present the clustering analysis of the final extended Baryon Oscillation Spectroscopic Survey (eBOSS) quasar sample at redshift 0.8<z<2.2\, which bridges the redshift gap between the eBOSS LRG and Lyman-alpha measurements. Mapping the evolution of the expansion and growth of structure histories of our Universe provides us with a crucial test of the standard LCDM cosmological scenario. Our analysis includes a detailed modelling of the impact of the non-linear evolution of density fluctuations\, bias\, and redshift-space distortions on the two-point correlation function. Using numerical simulations designed to reproduce the uniqueness of the quasar sample\, we perform extensive validation tests to characterise potential systematic errors induced by theoretical and observational effects. The constraints obtained from anisotropic clustering measurements can be used to test models of gravity on large-scales. However\, these tests require the validation of our analysis techniques in modified gravity scenarios. I present an example of such tests\, based on large numerical simulations of standard and modified gravity models to measure galaxy clustering in redshift space.

SUMMARY:Speaker: Ann-Kathrin Schutz - Eberhard Karls University of Tubingen
DESCRIPTION:Title: Full analysis of the background for the search of neutrinoless double beta decay in Gerda\n\nAbstract: The GERmanium Detector Array (Gerda) experiment aims for the discovery of neutrinoless double beta decay (0νββ) decay in 76Ge. It uses HPGe detectors enriched in the isotope 76Ge\, which are directly immersed into liquid argon (LAr). In second phase (Phase II) of Gerda\, the radio-pure cryogenic liquid acts not only as cooling medium for the detectors and passive shielding but also as active shielding. Phase II started data taking in Dec 2015 with the design goal of increasing the sensitivity to T 0ν1/2 = O1026 yr by reducing the background by one order of magnitude. Due to the active veto system detecting LAr scintillation light\, the superior energy resolution and an improved background recognition\, the initial release of Phase II already showed a background rate in the energy region of interest (ROI)\, after pulse shape discrimination (PSD) and liquid argon veto cuts\, in the range of a few counts/(ROI·ton·yr). This made Gerda the first 0νββ experiment being background free up to its design exposure of 100 kg·yr. With the latest data release in mid 2018\, comprising a total exposure of 82.4 kg·yr\, Gerda remained in the background free regime and it is the first experiment to surpass a median sensitivity on the half-life of 1026 yr for 0νββ decay. \nIn this talk\, a full analysis of the background is presented where all available information on the background has been incorporated in order to develop a detailed background model describing the decomposition of the measured energy spectrum. For the first time\, the single- and two-detector data have been combined in a multivariate Bayesian fit approach. Additionally\, the background model focuses further on two prominent features in the energy spectrum: the α events dominating the high energy part of the spectrum and the count rates of the potassium γ-lines at 1525 keV and 1461 keV. Thanks to the granularity of the detector array\, a study of the coincident events in the two-detector data which can provide further information regarding the location of contaminations has been integrated. Using the background model\, important information on the main sources and their locations contributing to the background around\nthe Q-value of the decay (Qββ) can be deduced. Besides\, the spectral shape of the total background around Qββ can be extracted. Both are crucial input informations for reliable results on the 76Ge 0νββ signal search.

SUMMARY:Special INPA SEMINAR - Karthik Ramanathan (University of Chicago)
DESCRIPTION:Speaker: Karthik Ramanathan (University of Chicago)\n \n\nTitle: Dark Matter Taking Selfies: The DAMIC Experiment \n\nAbstract: The DAMIC (Dark Matter in CCDs) experiment uses silicon charge-coupled devices (CCDs)\, traditionally employed for imaging purposes\, to detect potential ionization signals from dark matter interactions. These approx. mm thick devices feature an impressively low leakage current (< 10-21 A/cm2) and a very low energy threshold (40 eVee)\, making them ideal low-mass dark matter detectors. In addition\, their unique spatial resolution provides for effective identification and mitigation of environmental backgrounds. In this talk\, I will highlight recent dark matter-electron scattering limits from the experiment at SNOLAB\, discuss the kg-size next generation DAMIC-M detector funded for operation\, and show results from “Skipper”instrumented CCDs – a novel readout technique that allows for counting of individual charges\, with a demonstrated resolution of 0.07 e-\, which ushers in a new era of sensitivity to low-energy interactions.

SUMMARY:INPA Seminar - Harikrishnan Ramani (LBNL)
DESCRIPTION:Speaker: Harikrishnan Ramani (LBNL)\n \nTitle: Nuclear Isomers as Dark Matter accelerators\nAbstract: Weak-scale dark matter particles\, in collisions with nuclei\, can mediate transitions between different nuclear energy levels. In particular\, owing to sizeable momentum exchange\, dark matter particles can enable de-excitation of nuclear isomers that are extremely long lived with respect to regular radioactive decays. In this paper\, we utilize data from a past experiment with $^{\rm 180m}$Ta to search for $\gamma$-lines that would accompany dark matter induced de-excitation of this isomer. Non-observation of such transitions above background yields the first direct constraint on the lifetime of $^{\rm 180m}$Ta against DM-initiated transitions: $T_{1/2}>1.3\times 10^{14}$~a at 90\% C.I. Using this result\, we derive novel constraints on dark matter models with strongly interacting relics\, and on models with inelastic dark matter particles. Existing constraints are strengthened by this independent new method. The obtained limits are also valid for the Standard Model $\gamma$-decay of \nuc{Ta}{\rm 180m}.

SUMMARY:Speaker: Vishal Gajjar (UC Berkeley)
DESCRIPTION:Title: Breakthrough Listen’s search for intelligent life in the Universe \n\n\nAbstract: The discovery of the ubiquity of habitable extrasolar planets\, combined with revolutionary advances in instrumentation and observational capabilities\, have ushered in a renaissance in the millennia-old quest to answer our most profound question about the Universe and our place within it – Are we alone? The Breakthrough Listen Initiative announced in July 2015 as a 10-year 100M USD program is the most comprehensive effort in history to quantify the distribution of advanced\, technologically capable life in the universe. In this talk\, I outline the status of the on-going observing campaign with our primary observing facilities\, as well as planned activities with these instruments over the next few years. I will also talk about collaborative facilities which will conduct searches for technosignatures in either primary observing mode or commensally. I will highlight some of the novel analysis techniques we are bringing to bear on multi-petabyte data sets\, including machine learning tools we are deploying to search for a broader range of technosignatures than was previously possible. https://arxiv.org/abs/1907.05519

SUMMARY:Special INPA SEMINAR - Wouter Van De Pontseele (Harvard/Oxford)
DESCRIPTION:Speaker: Wouter Van De Pontseele (Harvard/Oxford)\n \n\nTitle: The MicroBooNE Neutrino Experiment at Fermilab\n\nAbstract: MicroBooNE is a liquid argon time projection chamber in the Booster Neutrino Beam at Fermilab. The technology provides high-resolution imaging of neutrino interactions leading to low-threshold event reconstruction with full angular coverage. As such\, this is an ideal place to probe neutrino-argon interactions in the hundreds-of MeV to few-GeV energy range. This talk presents a start-to-end overview demonstrating the physics capabilities of the detector. I will talk about cosmic ray measurement and characterisation\, our dominant background. \nFurthermore\, I will describe the flavour-agnostic neutrino pre-selection\, based on the combination of the charge collected by the TPC and the optical information form the PMT system. An overview of recent measurements of neutrino interactions in MicroBooNE\, including inclusive charged-current interactions\, will be given. I will conclude summarising the ongoing efforts towards our first low-energy-excess results\, demonstrating our capability to identify electron neutrinos.

SUMMARY:INPA Seminar - Chiara Capelli (University of Zurich)
DESCRIPTION:Speaker: Chiara Capelli (University of Zurich)\nTitle: Data analysis at high-energies for the XENON1T experiment and light calibration system of XENONn \nAbstract: The XENON1T experiment searches for Weakly Interacting Massive Particles (WIMPs) with a dual-phase xenon Time Projection Chamber (TPC). To extend its physics reach\, the efforts of the XENON collaboration are directed toward exploring other detection channels. For this purpose\, considerable work on the signal reconstruction and data analysis has been done to extend the available energy range up to 3\\,MeV\, two orders of magnitude higher than the standard WIMP analysis. This would allow one to search for the neutrinoless double beta decay (0$\nu\beta\beta$) of $^{136}$Xe\, which is fundamental to probing the Majorana nature of neutrinos and solving the hierarchy problem. The achievements and future prospects for the high-energy analysis with dual-phase TPCs will be presented. Furthermore\, the upcoming XENONnT experiment\, an upgrade of XENON1T with a larger TPC and reduced background\, is expected to start taking data in 2020. Its main goal is to increase the sensitivity to WIMPs by an order of magnitude compared to the current best limit\, as well as improving the search for 0$\nu\beta\beta$. An overview of the new systems\, with attention on the light calibration of the 494 photomultiplier tubes (PMTs) will be also presented. \n

SUMMARY:Special INPA Seminar – Gulden Othman (University of North Carolina)
DESCRIPTION:Speaker: Gulden Othman (University of North Carolina) \nTitle: CAGE Scanner: Investigating Surface Backgrounds in HPGe Detectors for Neutrinoless Double-Beta Decay Searches \nAbstract: A potential source of problematic backgrounds in a ton-scale 76Ge-based neutrinoless double-beta decay (0nuBB) program may arise from particle interactions occurring near the surfaces of high purity germanium (HPGe) detectors. The Collimated Alphas\, Gammas\, and Electrons scanner (CAGE) is a test stand that allows for in-depth studies of surface events by using vacuum-side\, collimated radiation sources to characterize the response of HPGe detectors to radiation at specific locations on the detector surface. LEGEND is a search for 0nuBB in the 76Ge isotope that will begin operation of a 200 kg array in 2021\, with a plan to scale up to 1000 kg of 76Ge-enriched HPGe detectors in a phased approach. In order to reach LEGEND-1000’s goal of a half-life sensitivity >10^28 years\, understanding and discriminating against backgrounds from surface events is essential. I will motivate the design and current status of CAGE in the context of LEGEND as we begin characterizing the response of two detector geometries that will be used in LEGEND to surface alpha interactions.

SUMMARY:Special INPA SEMINAR – Rebecca Carney (SLAC)
DESCRIPTION: \nSpeaker: Rebecca Carney (SLAC)\n \n\n\nTitle: Silicon tracking in the search for rare processes \n \nAbstract: The ATLAS Detector\, below the surface of the Swiss-French border\, measures the remnants of high-energy proton-proton collisions\, accelerated by the Large Hadron Collider (LHC) at CERN. A little over a year ago the LHC paused operations\, having delivered an integrated luminosity corresponding to 150 fb^−1 of data at a centre-of-mass energy of 13 TeV. This talk will describe a search for physics beyond the Standard Model using that dataset\, as well as the charged particle tracking detector technology that renders it possible.\n\nSearching for rare processes requires sifting through a large amount of data\, so in 2027 the LHC will enter a High Luminosity phase (HL-LHC)\, increasing the instantaneous luminosity by a factor of five and delivering 4000 fb^-1 within twelve years. This will impose significant technical challenges on all aspects of the ATLAS detector\, resulting in the entire Inner Detector being replaced by an all-silicon tracker. ITk (the new “Inner TracKer”) will be comprised of Strip and Pixel detectors. This talk will also discuss the design of the ITk Pixel detector to handle the increased number of hits per chip and modeling of the damage to the silicon sensor\, both to predict the detector performance and to understand the effects of radiation damage on data taking.

SUMMARY:VIRTUAL INPA SEMINAR – Zara Bagdasarian (UC Berkeley)
DESCRIPTION:Speaker: Zara Bagdasarian (UC Berkeley)\n\n\n\nTitle: Borexino. Sun. Earth. Neutrinos\n\n\nAbstract: \nBorexino experiment is a 280-ton liquid scintillator detector located at a 3800 m w.e. depth in the Laboratori Nazionali del Gran Sasso (Italy). In more than 12 years of data taking\, Borexino has demonstrated how its unprecedented radio-purity led to exploring a wide range of neutrino physics questions in previously poorly explored low energy range.\n\n\n\n\n\n\n\n\n\n\n\n\nIn 2018-2020\, Borexino published a comprehensive study of pp-chain solar neutrinos\, which sets new milestones in the solar neutrino measurement precision. These neutrinos are the products of the pp-chain of nuclear fusion reactions generating more than 99% of the Sun’s energy. We use the gathered data as a two-fold tool to explore both neutrino and solar physics questions.\n\n\n\n\n\n\n\n\nMoreover\, Borexino is one of only two detectors in the world who have measured geoneutrinos. The results\, published in 2020\, feature increased statistics and the new elaborate analysis. With this update\, we have now been able to access 53 geoneutrino events – almost twice as many as in the result published by the collaboration in 2015. The geological interpretations of this measurement will also be discussed in the talk.\n\n\n\n\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/812787340\n\nMeeting ID: 812 787 340

SUMMARY:VIRTUAL INPA SEMINAR – Nicholas Rodd (LBNL) - URL and Meeting ID Revision
DESCRIPTION:Speaker: Nicholas Rodd (LBNL) \n  \nTitle: Evidence the 3.5 keV line is not from dark matter decay \nAbstract: \nX-ray observations of nearby clusters and galaxies have reported an unexpected X-ray line around 3.5 keV. This line has received significant attention due to its possible explanation through decaying dark matter; in particular\, decaying sterile neutrino models\, with a sterile neutrino mass around 7 keV\, provide a good fit to the available data. We use over 30 Ms of XMM-Newton blank-sky observations to search for evidence of the 3.5 keV line consistent with arising from decaying dark matter within the ambient halo of the Milky Way. We find the strongest limits to-date on the lifetime of dark matter in this mass range\, strongly disfavoring the possibility that the 3.5 keV line originates from dark matter decay. \nREVISION – URL AND MEETING ID \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/993531175\nMeeting ID: 993 531 175

SUMMARY:VIRTUAL INPA SEMINAR – Ethan Bernard (UC Berkeley)
DESCRIPTION:Speaker: Ethan Bernard (UC Berkeley) \nTitle: The Construction of the LZ Dark Matter Detector \nAbstract: \n\nThe assembly of the LUX-ZEPLIN (LZ) dark matter detector within the Homestake mine in Lead\, South Dakota is nearing completion.  This detector features a two-phase time projection chamber containing seven tons of liquid xenon specifically instrumented to detect low-energy nuclear recoils.  The detector is nested within an active veto system\, a passive water shield\, and 1500 m of rock overburden.  Low-background construction and efficient measurement of scintillation light and ionization electrons will allow detection of hypothetical WIMP (weakly interacting massive particle) dark matter to a sensitivity at least an order of magnitude beyond present limits.  This talk will provide an overview of the design and assembly of this detector with a focus on the unique engineering challenges posed by building a low-background noble liquid experiment at such a large scale.\n\n\n\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/92275279117\nMeeting ID: 922 7527 9117

SUMMARY:VIRTUAL INPA SEMINAR – Rémi Adam (LLR/CNRS)
DESCRIPTION:Speaker: Rémi Adam (LLR/CNRS) \nTitle: Diffuse gas in galaxy clusters: on the thermal and non-thermal components \nAbstract: \nThe clusters of galaxies represent the last step of the formation of large scale structures in the Universe. They are both useful cosmological probes and unique astrophysical laboratories. The clusters grow by accretion of surrounding structures and from the merging of subclusters\, in very energetic events\, eventually forming a diffuse gas phase made of a hot thermal component\, but also leading to particle acceleration up to very high energies. After introducing the role of clusters in our understanding of the assembly of matter in the Universe\, I will discuss how we can study the diffuse gas phase across cosmic time. The presentation will highlight results based on the NIKA/NIKA2 camera at the IRAM 30m telescope\, sensitive to the thermal gas pressure via the Sunyaev-Zel’dovich effect.

SUMMARY:VIRTUAL INPA SEMINAR - Chia-Cheng Chang (LBNL)
DESCRIPTION:Speaker: Chia-Cheng Chang (LBNL) \n Title: Time evolution of open quantum many-body systems \nAbstract: \nThe increasing interest and efforts put forth towards the development of quantum computing have lead to a shift in how one goes about tackling problems that are typically thought of as difficult. In this talk I will discuss a specific paradigm of quantum computing called adiabatic quantum computing\, and narrow the scope to discuss what is known as quantum annealing. In particular\, the first part of the talk will be devoted to discussing what quantum annealing is\, and its connection with adiabatic quantum computing. I will follow by discussing the scope of problems that quantum annealers can hope to solve\, include an example for tackling integer linear programming. I will end by discussing our simulation of an open quantum many-body system and compare against experimental results obtained from a DWave quantum annealer. On the DWave\, we employ a modified time evolution schedule and observe an improvement in performance. Results from the simulation provide a possible explanation of the underlying physics by correlating algorithmic improvements to the interplay between quantum decoherence and many-body localization.. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/99612217893\nMeeting ID: 996 1221 7893

SUMMARY:VIRTUAL INPA SEMINAR – Eric Charles (Stanford) - Friday\, May 22\, 2020
DESCRIPTION:Speaker: Eric Charles (Stanford)\n\n\n\nTitle: Indirect Dark Matter Detection: Status and Summary of WIMP Searches  \n\n \n\nAbstract: \nThe nature of dark matter is a longstanding enigma of physics; it may consist of particles beyond the Standard Model that are still elusive to experiments. Searches for signals from the annihilation or decay of weakly interacting massive particle (WMIP) dark matter using observations of the gamma-ray sky have come to prominence over the last decade.    Current and upcoming telescopes such as the Fermi Large Area Telescope (Fermi-LAT) and the Cerenkov Telescope Array are particularly well suited for searching for products of the interactions of dark matter particles.  In this talk I will describe astrophysical targets studied for evidence of dark matter\, and review the status of these searches.  I will also discuss the factors that determine the sensitivities of these searches\, including the magnitudes of the signals and the relevant backgrounds\, considering both statistical and systematic uncertainties.  Finally\, I will discuss how upcoming observatories operating across the electromagnetic spectrum could change this field. \n \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91138499248\nMeeting ID: 911 3849 9248

SUMMARY:VIRTUAL INPA SEMINAR – Luca Pagani (UC Davis)
DESCRIPTION:Speaker: Luca Pagani (UC Davis) \nTitle: Recent results from the ACED and the ARTIE experiments \nAbstract: \nLiquid argon is becoming a popular medium for particle detection\, with applications ranging from low-background dark matter searches to high-energy neutrino detection. Because neutrons represent both an important source of background (e.g.\, for dark matter experiments) and a product of signal events (e.g.\, neutrino-induced spallation neutrons)\, a good understanding of their interactions in argon is a requirement for precision physics measurements. Despite being one of the most basic quantities needed to describe low-energy neutron transport\, the neutron cross section on argon is not clearly understood. In particular\, the existing activation measurements for the thermal neutron capture cross section show significant disagreements. Moreover\, in the energy range 40-70 keV theory predicts an anti-resonance in the $^{40}$Ar cross section near $57$\\,keV\, but the existing data\, coming from an experiment performed in the 90s (Winters. et al.)\, does not support this. To resolve these disagreements\, two experiments were performed using a time of flight neutron beam at Los Alamos National Laboratory. The Argon Capture Experiment at DANCE (ACED) first measured the differential cross section of $^{40}$Ar$(n\,\gamma)^{41}$Ar using the Detector for Advanced Neutron Capture Experiments (DANCE)\, a $\sim$4$\pi$ gamma spectrometer. A fit to the differential cross section from $0.015-0.15$\\,eV\, assuming a $1/v$ energy dependence\, yields $\sigma^{2200} = 673 \pm 26 \text{ (stat.)} \pm 59 \text{(sys.)}$\\,mb. Then\, the Argon Resonance Transmission Interaction Experiment (ARTIE) measured the transmission coefficient for neutrons through a thick ($\sim 3$\\,atoms/b) liquid natural argon target in the energy range 40-70 keV. This measurements are crucial for the Deep Underground Neutrino Experiment (DUNE) since allow a viable means of calibration and a deeper understanding of signals and backgrounds for the low energy science program. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/97119161552 \nMeeting ID: 971 1916 1552

The MAJORANA collaboration is searching for 0νββ in germanium-76 using a modular array of high-purity germanium detectors\, housed at the Sanford Underground Research Facility in Lead\, South Dakota. This presentation will show the results of an in-depth study of the backgrounds visible to the array\, and the details behind a model to explain their sources. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/99678795337 \nMeeting ID: 996 7879 5337

SUMMARY:VIRTUAL INPA SEMINAR – Jorge Morales (SLAC)
DESCRIPTION:Speaker: Jorge Morales (SLAC) \nTitle: Simulation of Dark Matter and Standard Model Interactions in the SuperCDMS Soudan Experiment  \nAbstract: \nAstronomical observations lead us to believe that dark matter constitutes the majority of the mass of the Universe\, yet it has never been directly observed experimentally. The Super Cryogenic Dark Matter Search Experiment (SuperCDMS) aims to discover the particle nature of dark matter\, by developing and using some of the most sensitive detectors ever built. Previous analyses with SuperCDMS set world leading sensitivity limits to dark matter interactions\, but the analysis techniques have not been based on simulations. Now we have developed an efficient simulations infrastructure that will help better understand the detectors\, develop a better background model\, and optimize the next generation dark matter searches. I present the fully-functional simulations infrastructure to produce high quality samples as well as results for the charge system readout simulations\, and comparisons to expectations from data. Whilst improvement is still needed\, I will show that our simulations well-reproduce dominant features of data\, bringing SuperCDMS closer to a robust simulation-based analysis method\, much needed for the upcoming SuperCDMS dark matter searches. \nJoin Zoom Meeting  \nhttps://lbnl.zoom.us/j/95746341336  \n Meeting ID: 957 4634 1336

SUMMARY:VIRTUAL INPA SEMINAR – Bradley Kavanagh (IFCA - Spain)
DESCRIPTION:Speaker: Bradley Kavanagh (IFCA – Spain) \nTitle: Detection Dark Matter around Black Holes with Gravitational Waves \nAbstract: The observation of Gravitational Waves (GWs) has opened up a whole new avenue for constraining and detecting particle Dark Matter (DM). One of the most promising systems to study is the Intermediate Mass Ratio Inspiral (IMRI): a stellar-mass compact object such as a neutron star inspiraling towards an intermediate mass black hole\, thousands of times more massive than the Sun. Sub-hertz GWs emitted during the inspiral should be detectable by future space-based observatories such as LISA. But the presence of DM in the system can have subtle dynamical effects on the inspiral\, altering the waveform and hopefully allowing us to map out the DM distribution. I will discuss ongoing work to study these systems carefully and self-consistently\, in order to determine whether such a signal can be detected and what we can learn about Dark Matter if it is. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95929756869 \nMeeting ID: 959 2975 6869

The latest calibration data sets with neutron and gamma-ray radioactive calibration sources will be discussed\, with implications reviewed on the extremely low energy threshold expected (sub-keV) and background discrimination as a function of thermodynamic conditions. The most recent three-dimensional image analysis will be shown with position reconstruction and multiple scattering. Information gathered from all prototypes will be analyzed together to form a projected sensitivity curve for both spin-independent and spin-dependent (proton) coupling. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/99047273608 \nMeeting ID: 990 4727 3608

SUMMARY:SPECIAL VIRTUAL INPA SEMINAR – Benjamin Schmidt (LBNL)
DESCRIPTION:Speaker: Benjamin Schmidt (LBNL) \nTitle: A new limit from the search for 0νββ of 100Mo from the CUPID-Mo experiment\n \nAbstract: The CUPID-Mo experiment\, currently taking data at the Laboratoire Souterrain de Modane (France)\, is a demonstrator for CUPID\, the next-generation upgrade of the first ton-scale cryogenic 0νββ-search\, CUORE. The experiment is searching for 0νββ decay of 100Mo with an array of 20 enriched ~0.2 kg Li2MoO4 crystals. The detectors are operated deep under the Frejus mountain at a depth of 4800 m.w.e. in a dilution refrigerator at ~20 mK. They are complemented by cryogenic Ge light detectors allowing us to distinguish alpha from beta/gamma events by the detection of both heat and scintillation light signals. With a bolometric performance of ~ 7 keV energy resolution (FWHM) at 2615 keV\, full alpha-to-beta/gamma separation and excellent radio-purity levels\, we operate in the background free regime. For the present analysis\, we consider more than one year of data acquired between March 2019 and April 2020. With 2.17 kg x yr of exposure and a high analysis efficiency of ~ 90%\, we are able to set a new world leading limit for 0νββ decay of 100Mo. In this seminar\, I will present the details of the analysis\, the new limit and I will conclude with an outlook on the end of CUPID-Mo data taking in July 2020 and further upcoming analyses. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/99340201217?pwd=eEJFSW9BN3pscm1FdDZ3cVpUODBoZz09 \nMeeting ID: 993 4020 1217 \nPassword: 211618

DESCRIPTION:Speaker: Michelle Galloway (University of Zurich) \nTitle: Observation of excess electronic recoil events in XENON1T \nAbstract: A search for new physics with XENON1T revealed an excess of electronic recoil events in the (1 – 7) keV region\, favoring signal over background with significances of 3.5 sigma for solar axions/ALPs\, 3.2 sigma for an enhanced neutrino magnetic moment\, and 3.0 sigma global (4.0 local) for bosonic dark matter with a peak at 2.3 +- 0.2 keV (68% C.L.). Additionally\, a previously undetected tritium component\, favoured at 3.2 sigma over known backgrounds\, can neither be confirmed nor excluded. I will provide an overview of the XENON1T detection and analysis methods for this search\, a characterization of the excess events\, and present results for both possible backgrounds and potential new physics. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98002426771?pwd=R3dtTFhmb0ZyR0ZHV1E5amZCcnFBZz09 \nMeeting ID: 980 0242 6771\nPassword: 531232

SUMMARY:VIRTUAL INPA SEMINAR – Hao Chen (Texas A&M University)
DESCRIPTION:Speaker: Hao Chen (Texas A&M University) \nTitle: Two New Cryogenic Detector R&D \nAbstract: It is well-accepted that the majority of the matter in the universe is dark and non-baryonic. The nature of dark matter\, however\, remains mysterious. Various proposed candidates span a wide range in the mass and cross section parameter space. Many experimental efforts have been made aiming to detect dark matter particles directly\, part of the region in the parameter space has been excluded from their data. Probing the lower mass region requires a low threshold detection technique. I will talk about two new cryogenic detectors that are currently under development. The magnetic bubble chamber utilizes a single-molecule magnet as the target\, amplifying the signal from a scattering event by magnetic avalanches. The phonon-mediated high-voltage detector combines features of CDMS iZip and HV detector\, provides a possible way to achieve a low threshold without losing the electron recoil/nuclear recoil discrimination. \nCORRECTION Updated meeting ID and password information \nJoin Zoom Meeting https://lbnl.zoom.us/j/96636700595?pwd=bWcvZU9MQmdYdzE1YzNrZXdROElJQT09 \nMeeting ID: 966 3670 0595  \nPassword: 419873

SUMMARY:VIRTUAL INPA SEMINAR – Gioacchino Ranucci (INFN) Italy
DESCRIPTION:Speaker: Gioacchino Ranucci (INFN) Italy \nTitle: First detection of solar neutrinos from the CNO cycle with Borexino \nAbstract: The liquid scintillator detector Borexino reported recently the direct observation of neutrinos produced in the carbon-nitrogen-oxygen (CNO) fusion cycle in the Sun. This is the first experimental evidence of the existence of such reaction sequence in a star. The CNO solar neutrino interaction rate is 7.2 +3.0 −1.7 counts per day per 100 tons of target at 68% C.L.\, corresponding to a flux of neutrinos on Earth of 7.0 +3.0 −2.0 ×108 cm−2 s −1. The absence of CNO signal is disfavored at 5.0σ. In this seminar\, I will describe the technological effort to stabilize the detector and understand the background\, which is at root of this achievement\, together with the main features of the analysis procedure exploited to extract the CNO signal. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/96603938296?pwd=UWZERUphMlVqS0hReVozQ2dFdjU1dz09 \nMeeting ID: 966 0393 8296\nPasscode: 484158
