Title: Resonant Forbidden Leptogenesis

Place: Seminar Room A
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 electroweak-scale leptogenesis that
is accessible at colliders, and dark matter cogenesis in the early universe.
