Kavli Affiliate: Takeo Higuchi | First 5 Authors: Alexander Aryshev, Ties Behnke, Mikael Berggren, James Brau, Nathaniel Craig | Summary: The International Linear Collider (ILC) is on the table now as a new global energy-frontier accelerator laboratory taking data in the 2030s. The ILC addresses key questions for our current understanding of particle physics. It […]

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: 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: Eiichiro Komatsu | First 5 Authors: Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim, Adriano Agnello, Ozgur Akarsu | Summary: In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological probes, such as the […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Hajime Fukuda, Hidetoshi Otono, Satoshi Shirai, , | Summary: One of the most promising methods to search for axions is a light-shining-through-walls (LSW) experiment. In this work, we discuss the possibility of performing an LSW experiment at the ILC experiment, where photon beams are generated for positron […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Maja Lujan Niemeyer, Eiichiro Komatsu, Chris Byrohl, Dustin Davis, Maximilian Fabricius | Summary: We present the median-stacked Lyman-$alpha$ surface brightness profile of 968 spectroscopically selected Lyman-$alpha$ emitting galaxies (LAEs) at redshifts $1.9<z<3.5$ in the early data of the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). The selected LAEs […]
Kavli Affiliate: Andrei Okounkov | First 5 Authors: David Kazhdan, Andrei Okounkov, , , | Summary: For a split reductive group ${}^L G$ over a global field, we determine the spectrum of the spherical Hecke algebra coming from the unramified Eisenstein series for the minimal parabolic ${}^L B$. This is done using a certain decomposition […]
