The Universe

Radiative neutrino mass models have interesting features, which make it possible to relate neutrino masses to the existence of dark matter. However, the explanation of the baryon number asymmetry in the universe seems to be generally difficult as long as we suppose leptogenesis based on the decay of thermal right-handed neutrinos. Since right-handed neutrinos are assumed to have masses of O(1) TeV in these models, they are too small to generate the sufficient lepton number asymmetry. Here we consider Affleck–Dine leptogenesis in a radiative neutrino mass model by using a famous flat direction LHu as an alternative possibility. The constraint on the reheating temperature could be weaker than the ordinary models. The model explains all the origin of the neutrino masses, the dark matter, and also the baryon number asymmetry in the universe.

Gauge Interaction

We reconsider a baryogenesis scenario in supersymmetric standard models with Dirac neutrinos proposed by Abel and Page. We introduce intermediate scale physics to stabilize the runaway potential along a right-handed sneutrino direction. If the lightest neutrino mass is small and/or thermal effects induce early oscillation, the right amount of baryon number asymmetry can be obtained even for higher reheating temperature without entropy production. We also discuss the right-handed sneutrino decay via SU (2)R gauge interaction as a solution to the problem of dark matter overproduction.
