On different approaches to freeze-in and freeze-out leptogenesis with quasi-degenerate neutrinos
Abstract We compare two approaches for determining the generation of lepton asymmetry during production and decay of quasi-degenerate neutrinos, namely the density matrix formalism and a recent proposal which does not involve any counting of neutrino number densities and is based on plugging the res...
