CUTE: A Cryogenic Underground TEst Facility at SNOLAB
Philippe Camus, Jonathan Corbett, Sean Crawford +14
Low-temperature cryogenics open the door for a range of interesting technologies based on features like superconductivity and superfluidity, low-temperature phase transitions or th…
The level-1 trigger for the SuperCDMS experiment at SNOLAB
Jonathan S. Wilson, Hanno Meyer zu Theenhausen, Belina von Krosigk +15
The SuperCDMS SNOLAB dark matter search experiment aims to be sensitive to energy depositions down to O(1 eV). This imposes requirements on the resolution, signal efficiency, and n…
Distinguishing Between Dark Matter and Pulsar Origins of the ATIC Electron Spectrum With Atmospheric Cherenkov Telescopes
Jeter Hall, Dan Hooper
Recent results from the Advanced Thin Ionization Calorimeter (ATIC) balloon experiment have identified the presence of a spectral feature between approximately 300 and 800 GeV in t…
Snowmass2021 Cosmic Frontier White Paper: Calibrations and backgrounds for dark matter direct detection
Daniel Baxter, Raymond Bunker, Sally Shaw +48
Future dark matter direct detection experiments will reach unprecedented levels of sensitivity. Achieving this sensitivity will require more precise models of signal and background…
Direct method for the quantitative analysis of surface contamination on ultra-low background materials from exposure to dust
M. L. di Vacri, I. J. Arnquist, S. Scorza +2
In this work we present a method for the direct determination of contaminant fallout rates on material surfaces from exposure to dust. Naturally occurring radionuclides K-40, Th-23…
The Next Generation of Photo-Detectors for Particle Astrophysics
Robert G. Wagner, Karen L. Byrum, Mayly Sanchez +6
We advocate support of research aimed at developing alternatives to the photomultiplier tube for photon detection in large astroparticle experiments such as gamma-ray and neutrino…
Report of the 2021 U.S. Community Study on the Future of Particle Physics (Snowmass 2021) Summary Chapter
Joel N. Butler, R. Sekhar Chivukula, André de Gouvêa +40
The 2021-22 High-Energy Physics Community Planning Exercise (a.k.a. ``Snowmass 2021'') was organized by the Division of Particles and Fields of the American Physical Society. Snowm…
A Search for Low-mass Dark Matter via Bremsstrahlung Radiation and the Migdal Effect in SuperCDMS
SuperCDMS Collaboration, Musaab Al-Bakry, Imran Alkhatib +128
In this paper, we present a re-analysis of SuperCDMS data using a profile likelihood approach to search for sub-GeV dark matter particles (DM) through two inelastic scattering chan…
A Consistent Dark Matter Interpretation For CoGeNT and DAMA/LIBRA
Dan Hooper, J. I. Collar, Jeter Hall +2
In this paper, we study the recent excess of low energy events observed by the CoGeNT collaboration and the annual modulation reported by the DAMA/LIBRA collaboration, and discuss…
Stellar Orbit Constraints on Neutralino Annihilation at the Galactic Center
Jeter Hall, Paolo Gondolo
Dark matter annihilation has been proposed to explain the TeV gamma rays observed from the Galactic Center. We study constraints on this hypothesis coming from the mass profile aro…
Snowmass 2021 Underground Facilities & Infrastructure Frontier Report
Laura Baudis, Jeter Hall, Kevin T. Lesko +1
The decade since Snowmass 2013 has seen extraordinary progress of high energy physics research performed--or planned for--at underground facilities. Drs. T. Kajita and A.B. McDonal…
