CP Violation from Scatterings with Gauge Bosons in Leptogenesis
Chee Sheng Fong, M. C. Gonzalez-Garcia, J. Racker
We present an explicit computation of the CP asymmetry in scattering processes involving the heavy right-handed neutrinos of the type I seesaw framework and the Standard Model gaug…
Supersymmetric Leptogenesis
Chee Sheng Fong, M. C. Gonzalez-Garcia, Enrico Nardi +1
We study leptogenesis in the supersymmetric standard model plus the seesaw. We identify important qualitative differences that characterize supersymmetric leptogenesis with respect…
Flavoured soft leptogenesis and natural values of the B term
Chee Sheng Fong, M. C. Gonzalez-Garcia, Enrico Nardi +1
We revisit flavour effects in soft leptogenesis relaxing the assumption of universality for the soft supersymmetry breaking terms. We find that with respect to the case in which th…
On fast CP violating interactions in leptogenesis
Chee Sheng Fong, J. Racker
We show that when the relevant CP violating interactions in leptogenesis are fast, the different matter density asymmetries are determined at each instant by a balance condition be…
