UV physics from IR features: new prospects from top flavor violation
Wolfgang Altmannshofer, Stefania Gori, Benjamin V. Lehmann +1
New physics in the rare top decays is currently very weakly constrained. We show that in a large class of Standard Model extensions, existing experimental co…
Directional detection of dark matter with anisotropic response functions
Christian Boyd, Yonit Hochberg, Yonatan Kahn +4
Direct detection for sub-GeV dark matter is developing rapidly, with many novel experimental ideas and theoretical methods emerging. In this work, we extend the dielectric formalis…
Report of the Topical Group on Particle Dark Matter for Snowmass 2021
Jodi Cooley, Tongyan Lin, W. Hugh Lippincott +71
This report summarizes the findings of the CF1 Topical Subgroup to Snowmass 2021, which was focused on particle dark matter. One of the most important scientific goals of the next…
Snowmass2021 Cosmic Frontier White Paper:Primordial Black Hole Dark Matter
Simeon Bird, Andrea Albert, Will Dawson +13
Primordial Black Holes (PBHs) are a viable candidate to comprise some or all of the dark matter and provide a unique window into the high-energy physics of the early universe. This…
Snowmass2021 Cosmic Frontier: The landscape of low-threshold dark matter direct detection in the next decade
Rouven Essig, Graham K. Giovanetti, Noah Kurinsky +90
The search for particle-like dark matter with meV-to-GeV masses has developed rapidly in the past few years. We summarize the science case for these searches, the recent progress,…
Dark Matter In Extreme Astrophysical Environments
Masha Baryakhtar, Regina Caputo, Djuna Croon +37
Exploring dark matter via observations of extreme astrophysical environments -- defined here as heavy compact objects such as white dwarfs, neutron stars, and black holes, as well…
Snowmass2021 Cosmic Frontier White Paper: Ultraheavy particle dark matter
Daniel Carney, Nirmal Raj, Yang Bai +25
We outline the unique opportunities and challenges in the search for "ultraheavy" dark matter candidates with masses between roughly and the Planck scale $m_{\rm pl}…
Light Quarks at Large
Daniel Davies, Michael Dine, Benjamin V. Lehmann
Lattice gauge theory simulations are our principal probe of the masses of the light quarks. Results from such computations are the primary evidence against the solution to…
New constraints on dark matter from superconducting nanowires
Yonit Hochberg, Benjamin V. Lehmann, Ilya Charaev +4
Superconducting nanowires, a mature technology originally developed for quantum sensing, can be used as a target and sensor with which to search for dark matter interactions with e…
Directional Detection of Light Dark Matter in Superconductors
Yonit Hochberg, Eric David Kramer, Noah Kurinsky +1
Superconducting detectors have been proposed as outstanding targets for the direct detection of light dark matter scattering at masses as low as a keV. We study the prospects for d…
Determining Dark Matter-Electron Scattering Rates from the Dielectric Function
Yonit Hochberg, Yonatan Kahn, Noah Kurinsky +3
We show that the rate for dark matter-electron scattering in an arbitrary material is determined by an experimentally measurable quantity, the complex dielectric function, for any…
Cosmological implications of the KOTO excess
Wolfgang Altmannshofer, Benjamin V. Lehmann, Stefano Profumo
The KOTO experiment has reported an excess of events above the Standard Model prediction, in tension with the Grossman-Nir (GN) bound. The GN bound heavily constr…
Cosmology and prospects for sub-MeV dark matter in electron recoil experiments
Benjamin V. Lehmann, Stefano Profumo
Dark matter is poorly constrained by direct detection experiments at masses below 1 MeV. This is an important target for the next generation of experiments, and several methods hav…
Direct detection of primordial black hole relics as dark matter
Benjamin V. Lehmann, Christian Johnson, Stefano Profumo +1
If dark matter is composed of primordial black holes, such black holes can span an enormous range of masses. A variety of observational constraints exist on massive black holes, an…
