SUMMARY:SPEAKER: Alexander Leder (UCB) – TITLE: Current status of the cavity and resonance based experiments
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: February 10\, 2023 \nTIME: 12:00 PM \nTITLE: Current status of the cavity and resonance based experiments \nABSTRACT: Axions are a well-motivated dark matter candidate\, which currently have a wide open and accessible parameter space\, with few constraints on their mass and coupling strength to photons. On the higher end of the mass range (> 1 GHz)\, experiments such as HAYSTAC or ADMX seek to measure the coupling of axions to the photon inside a resonant cavity\, making use of better than standard quantum limit sensors and very high Q values. On the lower end (between 5 kHz – 5 MHz)\, resonant experiments such The DMRadio-50L experiment seeks to explore a wide portion of this axion parameter space\, taking advantage of lumped element high-Q resonators with optimal out-of-band sensitivity. In this talk\, I will present an overview of the current status of the cavity and resonance based experiments currently underway to fully explore the over 22 orders of magnitude currently available to us. \nZOOM INFORMATION – \nJoin Zoom Meeting: https://lbnl.zoom.us/j/91782268585

SUMMARY:SPEAKER: R.G. Hamish Robertson (Univ of Washington)- TITLE: The direct road to neutrino mass
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: February 17\, 2023 \nTIME: 12:00 PM \nTITLE: The direct road to neutrino mass \nABSTRACT: The discovery of neutrino oscillations gave us proof that neutrinos have mass\, a direct contradiction of the minimal standard model of particle physics. But how much mass? Oscillations cannot give a number for the mass\, other than that the average of the three masses must be at least 0.02 eV. The mass is needed to build the new standard model\, and to help pin down such things as the equation of state of dark energy and the evolution of structure in cosmology. KATRIN\, the first new laboratory experiment on the beta spectrum of tritium in more than 20 years\, has now shown the mass to be no greater than 0.8 eV. KATRIN continues toward its sensitivity goal of 0.2 eV. If the mass is not in this range\, a very different approach called “Project 8” has passed proof-of-concept tests with a scheme that might have even greater sensitivity. \nZOOM INFORMATION – \nJoin Zoom Meeting:https://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEY\nmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

SUMMARY:Speaker: Daniel Carney (LBL)-TITLE: Proposal for a Levitated Invisible Particle Sensor
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: March 3\, 2023 \nTIME: 12:00 PM \nTITLE: Proposal for a Levitated Invisible Particle Sensor \nABSTRACT: Recently Dave Moore (Yale)\, Kyle Leach (Mines) and I proposed the use of a levitated mechanical quantum sensor combined with a pixelated electron/photon detector to look for invisible particles\, particularly heavy sterile neutrinos in the keV-MeV range. The basic device consists of ~100nm scale silica spheres implanted with radioisotopes. When the isotope decays\, via beta or electron capture\, it will generically eject e-/gammas as well as a neutrino which escape the nanosphere\, while the daughter atom is trapped in the sphere and causes it to recoil. With measurement precision on the sphere recoil at the “standard quantum limit”–which we have already achieved in a similar device at Yale–one can kinematically reconstruct the emitted neutrino momentum. I’ll outline how this works\, compare it to previous AMO-y approaches (e.g. HUNTER)\, and talk about what we’d like to do at LBL. \nZOOM INFORMATION – \nJoin Zoom Meeting:  https://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

SUMMARY:[EVENT CANCELED]:SPEAKER: Jonathan Echevers (UCB)-TITLE: The EXO program: Neutrinoless Double-Beta Decay Searches in Xe-136
DESCRIPTION:  \nEVENT CANCELED \nThis is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: March 17\, 2023 \nTIME: 12:00 PM \nTITLE: The EXO program: Neutrinoless Double-Beta Decay Searches in Xe-136 \nABSTRACT: Neutrinoless double beta (0vBB) decay is currently one of the most compelling searches in nuclear and particle physics. If found\, it would imply the existence of Majorana fermions and lepton number violation\, both new physics beyond the Standard Model. The EXO-200 experiment consisted of a time projection chamber (TPC) with 200 kg of enriched liquid xenon (LXe)\, optimized to search for 0vBB of Xe-136. Data acquisition took place from 2011 to the end of 2018\, with a total exposure of 234.1kg yr. We found no statistically significant evidence for 0vBB\, leading to a lower limit on the half-life of 3.5×10^25 yr at the 90% confidence level (CL). The ultra-low background necessary for this search also provides a unique opportunity to probe other exotic processes\, such as Lorentz violation in double-beta decay\, electron recoils from dark matter\, Majoron emitting modes of double-beta decay\, and others. The first part of this talk will focus on the EXO-200 experiment and recent results for exotic-physics searches using this detector. In the second half of this presentation I will discuss the next generation experiment\, nEXO\, a 5 tonne LXe TPC with a projected 0vBB half-life sensitivity of 1.35×10^28 yr at the 90% CL in 10 years of data-taking. \nZOOM INFORMATION – \nJoin Zoom Meeting:https://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEY\nmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: March 31\, 2023 \nTIME: 12:00 PM \nTITLE: Preparing for discovery of new physics with the Rubin Observatory  \nABSTRACT: The coming decade will offer a unique opportunity to tests physics using cosmological probes\, thanks to the new generation of galaxy surveys such as LSST by the Vera C. Rubin Observatory and CMB experiments. We will be able to test dark energy and the laws of gravity on cosmic scales with unprecedented precision\, both through the evolution of the background and growth of structures in the Universe. I will explain the multiprobe analysis we performed\, especially focusing on weak gravitational lensing\, and results we obtained using Dark Energy Survey data (arxiv:2207.05766)\, precursor of LSST. I will then describe how such analyses with future data are shaping and the gaps left to fill. I will end by describing the status of the Vera C. Rubin Observatory\, under construction in Chile and its future. \nZOOM INFORMATION – \nJoin Zoom Meeting:https://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEY\nmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

SUMMARY:SPEAKER: Noah Sailer (UC Berkeley)- Title: Accurate cosmology from CMB lensing and galaxy surveys
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate:  April 7\, 2023 \nTime: 12:00- 1:00 pm \nLocation:  Sessler Conference Room- 50A-5132 \n\nSpeaker: Noah Sailer (UC Berkeley) \nTitle: Accurate cosmology from CMB lensing and galaxy surveys \nAbstract: \nJoint analyses of CMB lensing and spectroscopically-calibrated galaxies have the ability to measure the evolution of matter fluctuations out to high redshifts without the complications of photometric redshift uncertainties and intrinsic alignments. These measurements are rapidly becoming one of the more powerful tools in a cosmologist’s toolkit\, enabling precise (and accurate) inference of cosmological parameters and potential deviations from ΛCDM. While cross-correlations are typically more robust against systematic effects\, correlated systematics arising from (extra)galactic foreground contamination and masking induce significant biases if not properly accounted for. I will discuss progress towards mitigating these effects\, the implementation of these methods in an ongoing cross-correlation analysis of DESI luminous red galaxies and CMB lensing from ACT\, and the prospects of future analyses with Stage-V spectroscopy and CMB-S4. \n  \nJoin Zoom Meeting\nhttps://lbnl.zoom.uspwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\n\nPasscode: 247722

SUMMARY:Speaker: Gabriela Rodrigues Araujo (University of Zurich)- Title: Light-sheet microscopy of color centers: A new venue for neutrino and dark matter detection with passive crystals
DESCRIPTION:SPECIAL INPA SEMINAR \nThis is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: April 10\, 2023 \nTIME: 4:00  pm \nTITLE: Light-sheet microscopy of color centers: A new venue for neutrino and dark matter detection with passive crystals \nABSTRACT: Most of the techniques currently used to detect nuclear recoils from dark matter and neutrinos rely on the collection of charge\, prompt scintillation photons or phonons. In this talk\, I will discuss a new approach: The use of light-sheet fluorescence microscopy to detect a specific type of crystal defect\, so called color centers (CCs)\, which could be induced by nuclear recoils in solid-state materials. Since CCs require little energy to form (10-50 eV)\, the proposed detectors can search for particle interactions at unexplored low-energy regions. Despite the nm-size of these defects\, excited CCs re-emit color in the visible range\, a feature that facilitates their detection. To make this detection channel competitive for rare-event search\, a fast imaging method of single CCs is necessary. The PALEOCCENE collaboration works towards this goal: a scalable read-out of CCs for passive detectors of neutrinos and dark matter. In the talk I will discuss the concept\, the current R&D and possible applications for dark matter\, CEvNS\, and nuclear-nonproliferation safeguards. \nZOOM INFORMATION – \nZoom Meeting\nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\n\nPasscode: 247722 \n

SUMMARY:SPEAKER: Lisa Schlueter (TU Munich)-TITLE: Neutrino-Mass Analysis with sub-eV Sensitivity and Search for Light Sterile Neutrinos with the KATRIN Experiment
DESCRIPTION:SPECIAL INPA SEMINAR \nThis is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: April 11\, 2023 \nTIME: 12:00  pm \nTITLE: Neutrino-Mass Analysis with sub-eV Sensitivity and Search for Light Sterile Neutrinos with the KATRIN Experiment \nABSTRACT: The KArlsruhe TRItium Neutrino (KATRIN) experiment is designed to determine the effective mass of the electron-antineutrino with a target sensitivity of 200 meV/c2 (90% C.L.) in a direct and model-independent way. KATRIN uses a strong gaseous windowless Tritium source associated with a large high-resolution spectrometer (MAC-E filter) to analyze precisely the electron energies from the source. The neutrino mass can be inferred from the shape of the tritium β-decay spectrum in the endpoint region. After global commissioning of the apparatus with Tritium in 2018\, KATRIN started its first neutrino mass measurement campaign in spring 2019. This talk presents the data and the analysis of the first two measurement campaigns. In terms of effective electron antineutrino mass\, an upper limit of 0.8 eV (90% C.L.) could be inferred\, reaching for the first time into the sub-eV regime. Moreover\, to exploit the full physics potential of the KATRIN experiment\, a search for light sterile neutrinos was conducted. As no sterile-neutrino signal is observed\, exclusion contours are drawn at 95% C.L. covering the parameter space of the long-persisting light-sterile neutrino anomalies to a great extent. \nZOOM INFORMATION – \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:SPEAKER: Prof. Christian Weinheimer (University of Münster)-TITLE: The dark matter experiment XENONnT and first WIMP results
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: April 14\, 2023 \nTIME: 12:00- 1:00 PM \nTITLE: The dark matter experiment XENONnT and first WIMP results \nABSTRACT: Evidence for about 6 times more matter in the universe than normal\nmatter is coming from cosmological observations and analyses on all\nscales. What this exotic dark matter is remains still a secret.\nThe direct search experiment for dark matter XENONnT located at the\nItalian underground laboratory LNGS is looking for weakly interacting\nmassive particles (WIMPs) and other rare event physics. As an upgrade of\nthe previous experiment XENON1T it uses a dual-phase time projection\nchamber with a total mass of 8.5t of liquid xenon. The recent electron\nrecoil data from a 1.16 t*yr exposure of XENONnT allowed to set\nstringent limits on solar axions\, an enhanced neutrino magnetic moment\nand bosonic dark matter. XENONnT’s unprecedented low background\noriginates from very careful material selecting and screening as well as\nfrom active removal of Kr-85 and Rn-222 by cryogenic distillation. This\nlow background rate allows for a rich physics search program with\nXENONnT with WIMPs being the main objective.\nIn this talk the status of the XENONnt experiment and its first WIMP\nsearch results from a blind analysis in an energy range between 3.1 keV\nand 60.0 keV and an exposure of approximately 1.1 tonne-year is presented.” \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

SUMMARY:Speaker: Antoine Armatol-Title:Investigation of the Majorana nature of neutrinos at a few meV level of the neutrino mass scale: from CUPID to BINGO
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: May 5\, 2023 \nTIME: 12:00- 1:00 PM \nTITLE: Investigation of the Majorana nature of neutrinos at a few meV level of the neutrino mass scale: from CUPID to BINGO \nABSTRACT: The search for neutrinoless double beta decay (0ν2β) is one of the biggest experimental challenges of contemporary physics. Its discovery would be ground- breaking since it would prove the Majorana nature of neutrinos\, give an insight into neutrino mass scale\, and provide clues to explain the matter/antimatter asymmetry of our Universe. Cryogenic calorimeters are promising devices for this purpose as CUORE\, the ton-scale experiment constructed with such detectors\, is demonstrating by setting the most stringent limit on Te-130 0ν2β half-life and being one of the most sensitive current generation experiments. However\, its sensitivity is limited by the background. Its successor\, the next-generation experiment CUPID\, will reach a higher sensitivity by reducing the number of expected background events in the region of interest. It will study as the candidate isotope Mo-100 embedded inside Li2MoO4 scintillating crystals\, which allows mitigating the Ɣ background naturally while also introducing a dual heat/light readout using an auxiliary Ge bolometer to get rid of the α background. Thanks to that\, CUPID will improve the CUORE sensitivity by two orders of magnitude. At that point\, if 0ν2β still eludes us\, the background reduction must be pushed even further. BINGO is a project aiming to prepare the next-next generation of bolometric experiments by proposing innovations and methods for that purpose. For example\, it will reduce the remaining Ɣ and β background contributions thanks to respectively a cryogenic active veto and a revolutionary detector assembly. BINGO will demonstrate that\, once implemented in a ton-scale isotope experiment\, its improvements will allow the latter to reach a sensitivity to neutrino mass scale below 10 meV. In that talk\, the current status of the CUPID experiment will be discussed and the R&D work done in the framework of the BINGO project will be presented. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

SUMMARY:Speaker: Raquel Castillo Fernandez (University of Texas Arlington)- Title: In the hunt for 0νββ at the NEXT experiment
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: May 12\, 2023 \nTIME: 12:00- 1:00 PM \nTITLE: In the hunt for 0νββ at the NEXT experiment \nABSTRACT: In the last decades\, oscillation experiments have demonstrated that neutrinos are not massless particles\, and the lepton number is not conserved. Thus\, revealing the nature of neutrino masses is one of the major goals in particle physics\, and the observation of the neutrinoless double beta decay (0νββ) has been identified as the most practical way to establish that neutrinos are Majorana particles\, that is\, fermions equivalent to their antiparticles. However\, 0νββ\, which would violate the lepton number by two units\, has not been observed yet and the best limits to the half-life of this process exceed 10ˆ26 yr. An extraordinary effort by several experimental collaborations is ongoing to achieve this ambitious goal and to explore the possibilities to understand the underlying physics of this process\, among them\, the NEXT experiment aims at the competitive search for the 0νββ decay in 136Xe using high-pressure gas electroluminescent time projection chambers (TPCs). In this talk\, I will discuss the status of the current prototypes that are under installation\, NEXT-100 and NEXT-CRAB\, and some of the main challenges and virtues of the 0νββ search. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

SUMMARY:[SPECIAL] Speaker: Roohi Dalal (Princeton University)- Title: Cosmology and Systematics from Hyper Suprime-Cam Year 3 Data
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room 50A-5132  \nDATE: June 2\, 2023 \nTIME: 12:00- 1:00 PM \nTITLE: Cosmology and Systematics from Hyper Suprime-Cam Year 3 Data \nABSTRACT: The Hyper Suprime-Cam (HSC) survey is the deepest Stage III weak lensing experiment\, going to ~26 mag with exquisite seeing. The depth and image quality achieved by HSC allow us to probe cosmology using weak lensing upto high redshifts\, and these analyses serve as important preparatory studies for the next generation of weak lensing surveys. I will discuss our constraints on cosmological parameters using weak lensing cosmic shear power spectra measured from the Year 3 shear catalog of HSC\, covering 416 square degrees of the northern sky. After giving a brief overview of our cosmological analysis\, and our new constraint on the S8 parameter\, I will focus on systematics that have been important and distinguishing factors in our analysis\, including photometric redshift uncertainties\, systematics from higher order PSF moments\, and uncertainties in the modeling of baryonic feedback. I will show that we have made a number of conservative choices to ensure that our analysis is robust to these systematics and share some lessons learned that will enable future surveys to hopefully no longer be limited by such systematics. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: INPA Common Room – 50- 5026 \nDATE: June 9\, 2023 \nTIME: 12:00- 1:00 PM \nTITLE: SPHEREx: NASA’s all-sky near-infrared spectral survey \nABSTRACT: SPHEREx is a NASA Astrophysics Explorer mission to produce a near-infrared all-sky spectrophotometric survey.   The 2-year mission will measure spectra of every 6-arcsecond pixel on the sky between 0.75 and 5 microns at spectral resolution varying between R=35 and 130.   SPHEREx’s instrument is based on a 30-cm off-axis telescope feeding six Teledyne H2RG detectors behind linear variable filters.  The mission is optimized to address three science themes: 1. Inflation in the early Universe through large scale structure\, 2. the history of galaxy formation by measuring spectra of the extragalactic background fluctuations\, and 3. the inventory of biogenic ices in our own Galaxy by surveying ice spectral absorption features towards stars.  This talk will describe the unique instrument and survey\, and address prospects for constraints on inflationary cosmology through a 3D galaxy redshift survey with the SPHEREx data. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

SUMMARY:Speaker: Ben Smithers (UTA)- Title: A Multi-Channel Search for Signatures of eV-Scale Sterile Neutrinos in IceCube
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler CR\, 50A-5132 \nDATE: June 16\, 2023 \nTIME: 12:00- 1:00 PM \nTITLE: A Multi-Channel Search for Signatures of eV-Scale Sterile Neutrinos in IceCube \nABSTRACT: The IceCube Neutrino Observatory is a cubic-kilometer-scale neutrino observatory built using a gigaton of instrumented ice near the Amundsen–Scott South Pole Station in Antarctica; it measures the Cherenkov light emitted by the daughter particles of neutrino-nucleon interactions occurring inside and around the detector from neutrinos of both astrophysical and atmospheric origin. For eV2-scale sterile neutrino models\, matter-effects can yield resonant $\bar{\nu}_{\mu}\to\bar{\nu}_{s}$ oscillations for TeV-scale up-going neutrinos. For certain combinations of mixing angles\, this is also expected to yield resonant $\bar{\nu}_{\mu}\to\bar{\nu}_{\tau}$ oscillations at the same energies and zeniths as the $\nu_{\mu}$ disappearance. This superimposed $\nu_{\mu}$ disappearance and $\nu_{\tau}$ appearance presents itself as an ideal signature with which we can search for indications of sterile neutrino oscillations. Here\, we discuss a multi-channel analysis searching for signs of both resonant muon neutrino disappearance as well as tau neutrino appearance. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

SUMMARY:Speaker: Barbara Skrzypek (Harvard)- Title:  Ice-Breaking Neutrino Energies: Astrophysical Messengers of Planck-Scale Physics​
DESCRIPTION:This is an In-Person [HYBRID] Event \nLocation: Sessler CR\, 50A-5132 \nDate: July 7\, 2023 \nTime: 12:00- 1:00 PM \nSpeaker: Barbara Skrzypek( Harvard) \nTitle:  Ice-Breaking Neutrino Energies: Astrophysical Messengers of Planck-Scale Physics​  \nAbstract: ​In recent decades\, particle physics has made significant advances in our understanding of high-energy phenomena\, both on theoretical and experimental fronts\, culminating in the current Standard Model (SM) of particle physics. However\, the SM is not a self-contained theory and leaves many questions unanswered; in particular\, it falls short of incorporating dark matter or gravitational forces. Among the implications for this is that\, beyond the quantum gravity scale\, we expect the SM to be replaced with a more fundamental theory giving a quantum description of gravity. As such\, effective theories that arise from this fundamental theory can break certain symmetries that normally hold in the SM\, such as Lorentz- and CPT-invariance . As a result of this\, we expect there to be observables that exhibit low-energy manifestations of these symmetry violations\, and in turn\, this could have implications for neutrinos and other astrophysical messengers. In this talk\, I give an overview of work that I have done in theory\, phenomenology\, and experimental high-energy physics in the area of effective theories of high-energy phenomena. In an effort to characterize the astrophysical neutrinos that IceCube has observed\, I discuss what we can learn about the physics that happens between the production of astrophysical particles and their subsequent detection. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

SUMMARY:Speaker: Jonathan Echevers (UC Berkeley)- Title: The EXO program: Neutrinoless Double-Beta Decay Searches in Xe-136
DESCRIPTION:DATE: August 4\, 2023 \nTIME: 12:00- 1:00 PM \nSPEAKER:  Jonathan Echevers (UC Berkeley)- Title: The EXO program: Neutrinoless Double-Beta Decay Searches in Xe-136 \nTITLE: The EXO program: Neutrinoless Double-Beta Decay Searches in Xe-136 \nABSTRACT: Neutrinoless double beta (0vBB) decay is currently one of the most compelling searches in nuclear and particle physics. If found\, it would imply the existence of Majorana fermions and lepton number violation\, both new physics beyond the Standard Model. The EXO-200 experiment consisted of a time projection chamber (TPC) with 200 kg of enriched liquid xenon (LXe)\, optimized to search for 0vBB of Xe-136. Data acquisition took place from 2011 to the end of 2018\, with a total exposure of 234.1kg yr. We found no statistically significant evidence for 0vBB\, leading to a lower limit on the half-life of 3.5×10^25 yr at the 90% confidence level (CL). The ultra-low background necessary for this search also provides a unique opportunity to probe other exotic processes\, such as Lorentz violation in double-beta decay\, electron recoils from dark matter\, Majoron emitting modes of double-beta decay\, and others. The first part of this talk will focus on the EXO-200 experiment and recent results for exotic-physics searches using this detector. In the second half of this presentation I will discuss the next generation experiment\, nEXO\, a 5 tonne LXe TPC with a projected 0vBB half-life sensitivity of 1.35×10^28 yr at the 90% CL in 10 years of data-taking. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

SUMMARY:Speaker: Damian Goeldi (ETH Zurich)- TITLE: Testing weak equivalence with the LEMING experiment
DESCRIPTION:DATE: August 11\, 2023 \nTIME: 12:00- 1:00 PM \nSPEAKER:  Damian Goeldi (ETH Zurich) \nTITLE: Testing weak equivalence with the LEMING experiment \nABSTRACT: The LEMING experiment aims to test weak equivalence in leptonic antimatter. We will employ atomic interferometry to measure the vertical deviation of a horizontal cold muonium (M = μ+ + e−) beam. Existing muonium production schemes are unsuitable for such a precise measurement due to their large velocity and angular spread. To overcome this limitation we have demonstrated a new technique leveraging the chemical potential of superfluid helium (SFHe) to produce a cold muonium beam with a very well defined velocity and angular spectrum. Due to the SFHe our particle detectors need to operate at temperatures below 1K. We have successfully achieved sub-kelvin operation of commercial silicon photomultipliers (SiPMs). Furthermore\, a strong background suppression is required in order to reach the intended sensitivity. This can be achieved via a reliable detection of the atomic electron from the muonium\, left over after the decay of the antimuon. However\, these electrons possess very low energies. Hence\, a second detector is required which not only operates below 1K\, but also features an energy detection threshold below 1keV. We are currently testing several candidate detectors including perovskite nanocrystals and superconducting nanowires. This talk will give an overview of the LEMING experiment with a focus on the cold muonium beam as well as the cryogenic particle detectors. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722
