Abstract:
Finite-temperature effects open more opportunities to explain the baryon asymmetry of the universe in minimal models beyond the standard model (SM). In this talk, I will introduce the forbidden CP asymmetry that is generated via soft-lepton resummation at finite temperatures and has a SM-predicted resonant enhancement. It features leptogenesis at the electroweak scale that is accessible at colliders, and dark matter cogenesis in the early universe.
