Lepton collider as a window to reheating via freezing in dark matter detection. Part I

Year: 2025

Type: article

Abstract: We propose a methodology to infer the reheat temperature ( T R H ) of the Universe from the collider signal of freezing in dark matter (DM). We demonstrate it for the mono- γ signal at the electron-positron colliders, which indicates to a low-scale T R H , after addressing observed DM abundance, BBN, and other relevant constraints. The method can be used to correlate different reheating dynamics, DM models, and collider signals.
