| アブストラクト: |
Thermal leptogensis provides a simple explanation of the cosmological matter-antimatter asymmetry. However, the thermal leptogenesis requires the very high reheating temperature of universe; TR> 10^10￣GeV, and we suffer from the overproduction of the gravtino in a supersymmetric standard model. I will explain that we can avoid the problem by considering the gauge mediated supersymmetry breaking models.
