SUMMARY:VIRTUAL INPA SEMINAR - Zachary Marshall (LBNL)
DESCRIPTION:Speaker: Zachary Marshall (LBNL) \n Title: Unidentified New Physics: LHC Searches for SUSY and Dark Matter \nAbstract: \nATLAS and CMS\, two large\, general-purpose experiments at the Large Hadron Collider at CERN\, have a rich program of searches for new physics. This seminar will take a look at some of the most interesting and difficult searches for Supersymmetry and Dark Matter performed to date. Along the way\, there will be some discussion of the difficulties in comparing LHC search results to non-collider search results\, and a look into some of the computing challenges that the experiments will face in the coming decade. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/99705341835\nMeeting ID: 997 0534 1835

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
