Title: D-term inflation and leptogenesis by a right-handed sneutrino

Abstract

We discuss a D-term inflation scenario where a right-handed sneutrino can be an inflaton field leading to a viable inflation and leptogenesis, with a minimal form of Kaehler potential. The decay of an inflaton sneutrino can nonthermally create large enough lepton asymmetry. Its entropy production is also big enough to ameliorate the gravitino problem caused by too high a reheating temperature from the decay of a symmetry breaking field.
