Abstract

The 2022 Snowmass Community Summer Study consisted of two years of engagement with the particle physics community to craft a US particle physics strategy for the next decade, culminating in the 2022 Snowmass Book. This Report of the Topical Group on Calorimetry forms the basis for a small section of the Snowmass Book dealing with the community's vision for calorimetry going forward. It is the distillation of ideas put forth in public meetings and numerous white papers already freely available. The Report describes particle flow and dual readout approaches, integration of precision timing, and trends in calorimetric materials, and highlights key research directions for the next decade.
