Title: Baryogenesis via left-right asymmetry generation by the Affleck-Dine mechanism in a Dirac neutrino model

Abstract

A baryogenesis scenario in supersymmetric standard models with Dirac neutrinos proposed by Abel and Page is reconsidered, introducing intermediate scale physics to stabilize the runaway potential along a right-handed sneutrino direction. Contrary to 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 also discuss the solution to the problem of dark matter overproduction from the right-handed sneutrino decay by SU(2){sub R} gauge interaction.
