Leptogenesis in a spatially flat Milnetype universe
The quantum electrodynamics on a spatially flat (1+3)dimensional FriedmannLemaitreRobertsonWalker spacetime with a Milnetype scale factor is considered focusing on the amplitudes of the allowed effects in the first order of perturbations. The definition of the transition rates is reconsidered obtaining an appropriate angular behavior of the probability of the pair creation from a photon which has a similar rate as the leptons creation from vacuum.
