Description
Unitarity and $CPT$ symmetry constrain the $CP$ asymmetries entering the Boltzmann equation for net particle number generation. These constraints often manifest as cancelations of the leading-order asymmetries in decays and scatterings. In this poster, we consider the asymmetries of seesaw type-I leptogenesis with top-Yukawa corrections. Even when starting with Maxwell-Boltzmann phase-space densities, some of the contributions required by unitarity and $CPT$ symmetry are interpreted as approximations of quantum statistics and thermal-mass effects. The work is based on JCAP10 (2022) 042.
