Affleck-Dine baryogenesis just after inflation
  We propose a new scenario of Affleck-Dine baryogenesis where a flat direction
in the MSSM generates B-L asymmetry just after the end of inflation. The
resulting amount of baryon asymmetry is independent of low-energy
supersymmetric models but is dependent on inflation models. We consider the
hybrid and chaotic inflation models and find that reheating temperature is
required to be higher than that in the conventional scenario of Affleck-Dine
baryogenesis. In particular, non-thermal gravitino-overproduction problem is
naturally avoided in the hybrid inflation model. Our results imply that
Affleck-Dine baryogenesis can be realized in a broader range of supersymmetry
and inflation models than expected in the literature.
