Gravitino cosmology helped by a right handed (s)neutrino
In this paper, we discuss interesting scenarios resulting from the interplay between the gravitino and the lightest right-handed (s)neutrino. We consider two gravitino mass regimes vastly separated, that is, m3/2=O(100) eV and m3/2≃100 GeV. For the former case, a significant amount of the entropy pr...
