The decay of an inflaton sneutrino can non-thermally 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.References addedHigh Energy Physics - PhenomenologyAstrophysicsHigh Energy Physics - TheoryD-term Inflation and Leptogenesis by Right-handed Sneutrinotext
