Minimal Lepton Flavour Violation and Leptogenesis — •Selma Uhlig — TU Muenchen, Muenchen, Deutschland

We analyze lepton flavour violation (LFV), as well as generation of the observed baryon-antibaryon asymmetry of the Universe (BAU) within a generalized minimal lepton flavour violation (MLFV) framework as proposed recently in the literature. We allow for CP violation both at low and high energies. The generation of BAU is obtained through radiative resonant leptogenesis (RRL), starting with three exactly degenerate right-handed neutrinos at the GUT scale, the splittings between their masses at the Majorana scale are generated by renormalization group effects and turn out to be sufficient for a successful leptogenesis widely independent of the Majorana scale. Flavour specific effects are relevant. Correlations to LFV processes like mu -> e gamma are discussed.
