Kavli Affiliate: Tom Melia, Shigeki Matsumoto | First 5 Authors: Tsuguo Aramaki, Mirko Boezio, James Buckley, Esra Bulbul, Philip von Doetinchem | Summary: This white paper discusses the current landscape and prospects for experiments sensitive to particle dark matter processes producing photons and cosmic rays. Much of the gamma-ray sky remains unexplored on a level […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Rebecca K. Leane, Seodong Shin, Liang Yang, Govinda Adhikari, Haider Alhazmi | Summary: Intriguing signals with excesses over expected backgrounds have been observed in many astrophysical and terrestrial settings, which could potentially have a dark matter origin. Astrophysical excesses include the Galactic Center GeV gamma-ray excess detected […]
Kavli Affiliate: Jia Liu | First 5 Authors: Eric J. Baxter, Chihway Chang, Andrew Hearin, Jonathan Blazek, Lindsey E. Bleem | Summary: Cosmological data in the next decade will be characterized by high-precision, multi-wavelength measurements of thousands of square degrees of the same patches of sky. By performing multi-survey analyses that harness the correlated nature […]

Kavli Affiliate: Lina Necib | First 5 Authors: Shin’ichiro Ando, Sebastian Baum, Michael Boylan-Kolchin, Esra Bulbul, Michael Burgess | Summary: This whitepaper focuses on the astrophysical systematics which are encountered in dark matter searches. Oftentimes in indirect and also in direct dark matter searches, astrophysical systematics are a major limiting factor to sensitivity to dark […]
Kavli Affiliate: Tom Melia, Hitoshi Murayama | First 5 Authors: Simone Alioli, Radja Boughezal, Weiguang Cao, Gauthier Durieux, Lukáš Gráf | Summary: In this contribution to the Snowmass 2021 process we review theoretical developments in the Standard Model Effective Field Theory (SMEFT) with a focus on effects at the dimension-8 level and beyond. We review […]
Kavli Affiliate: Edward Kolb | First 5 Authors: Daniel Carney, Nirmal Raj, Yang Bai, Joshua Berger, Carlos Blanco | Summary: We outline the unique opportunities and challenges in the search for "ultraheavy" dark matter candidates with masses between roughly $10~{rm TeV}$ and the Planck scale $m_{rm pl} approx 10^{16}~{rm TeV}$. This mass range presents a […]

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Emanuele Berti, Vitor Cardoso, Zoltán Haiman, Daniel E. Holz, Emil Mottola | Summary: Gravitational wave detectors are formidable tools to explore strong-field gravity, especially black holes and neutron stars. These compact objects are extraordinarily efficient at producing electromagnetic and gravitational radiation. As such, they are ideal […]
