Thermal masses in leptogenesis
arXiv:0910.4872 · doi:10.1063/1.3327783
Abstract
We investigate the validity of using thermal masses in the kinematics of final states in the decay rate of heavy neutrinos in leptogenesis calculations. We find that using thermal masses this way is a reasonable approximation, but corrections arise through quantum statistical distribution functions and leptonic quasiparticles.
