Leptogenesis in the minimal flipped SU(5) (5) unification
Original language description
We study the prospects of thermal leptogenesis in the framework of the minimal flipped SU(5) ( 5 ) unified model in which the right-handed (RH) neutrino mass scale emerges as a two-loop effect. Despite its strong suppression with respect to the unification scale that tends to disfavor leptogenesis in the standard Davidson-Ibarra regime (and a notoriously large washout of the N 1-generated asymmetry owing to a toplike Yukawa entry in the Dirac neutrino mass matrix) the desired eta B similar to 6 x 10 - 10 can still be attained in several parts of the parameter space exhibiting interesting baryon and lepton number violation phenomenology. Remarkably enough, in all these regions the mass of the lightest left-handed (LH) neutrino is so low that it yields m beta less than or similar to 0.03 eV for the effective neutrino mass measured in beta decay, i.e., an order of magnitude below the design sensitivity limit of the KATRIN experiment. This makes the model potentially testable in the near future.
