Implications of residual CP symmetry for leptogenesis in a model with two right-handed neutrinos

We analyze the interplay between leptogenesis and residual symmetry in the framework of a model with two right-handed neutrinos. Working in the flavor basis, we show that all the leptogenesis CP asymmetries are vanishing for the case of two residual CP transformations or a cyclic residual flavor sym...
