Presented at the July 2021 Snowmass Process, this paper describes the frontier of physics theories for the next decade, presenting problems with the Standard Model of physics and the condition that the BSM (“beyond the standard model”) will need to meet. This includes the asymmetry of matter and dark matter within the universe, a reason behind the flavor structures of subatomic quarks and leptons, and “the origin of the neutrino masses.”
