dc.descriptionA baryogenesis scenario in supersymmetric standard models with Dirac neutrinos proposed by Abel and Page is reconsidered with introducing intermediate scale physics to stabilize the runaway potential along a right-handed sneutrino direction. In contrary with previous results, the baryon number asymmetry can be explained even for higher reheating temperature without entropy production if the lightest neutrino mass is small and/or thermal effects induce early oscillation. We discuss the solution to the problem of dark matter overproduction by the right-handed sneutrino decay by SU(2)_R gauge interaction.
