VIRTUAL INPA SEMINAR – Chia-Cheng Chang (LBNL)

Speaker: Chia-Cheng Chang (LBNL)  Title: Time evolution of open quantum many-body systems Abstract: The 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 […]

VIRTUAL INPA SEMINAR – Eric Charles (Stanford) – Friday, May 22, 2020

Speaker: Eric Charles (Stanford) Title: Indirect Dark Matter Detection: Status and Summary of WIMP Searches     Abstract:  The 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) […]

VIRTUAL INPA SEMINAR – Luca Pagani (UC Davis)

Speaker: Luca Pagani (UC Davis) Title: Recent results from the ACED and the ARTIE experiments Abstract: Liquid 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 […]

VIRTUAL INPA SEMINAR – Micah Buuck (SLAC)

Speaker: Micah Buuck (SLAC) Title: Neurtrinoless Double-Beta Decay and Radioactive Backgrounds in the MAJORANA DEMONSTRATOR Abstract: Neutrinoless double-beta decay (0νββ) is a lepton-number-violating process whose existence would indicate that neutrinos are Majorana fermions. The MAJORANA collaboration is searching for 0νββ in germanium-76 using a modular array of high-purity germanium detectors, housed at the Sanford Underground […]

VIRTUAL INPA SEMINAR – Jorge Morales (SLAC)

Speaker: Jorge Morales (SLAC) Title: Simulation of Dark Matter and Standard Model Interactions in the SuperCDMS Soudan Experiment Abstract: Astronomical 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 […]

VIRTUAL INPA SEMINAR – Bradley Kavanagh (IFCA – Spain)

Speaker: Bradley Kavanagh (IFCA - Spain) Title: Detection Dark Matter around Black Holes with Gravitational Waves Abstract: 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 […]

VIRTUAL INPA Seminar – Matthew Szydagis (UALbany)

Speaker: Matthew Szydagis (UALbany) Title: The Road to Discovering Sub-GeV Dark Matter Using Supercooled Liquids Abstract:The latest developments in the search for low-mass dark matter with the snowball chamber technology, essentially a reverse bubble chamber using supercooled water instead of superheating, will be presented. The latest calibration data sets with neutron and gamma-ray radioactive calibration […]

SPECIAL VIRTUAL INPA SEMINAR – Benjamin Schmidt (LBNL)

Speaker: Benjamin Schmidt (LBNL) Title: A new limit from the search for 0νββ of 100Mo from the CUPID-Mo experiment Abstract: 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.

VIRTUAL INPA SEMINAR – Hao Chen (Texas A&M University)

Speaker: Hao Chen (Texas A&M University) Title: Two New Cryogenic Detector R&D Abstract: 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 […]
