Nonthermal production of dangerous relics in the early universe
The excessive production of gravitinos in the early universe destroys the successful predictions of nucJeosynthesis. The thermal generation of gravitinos after inflation leads to the bound on the reheating temperature, TRH ;S 109 GeV. In this talk we investigate the non-thermal generation of graviti...

| description | The excessive production of gravitinos in the early universe destroys the successful predictions of nucJeosynthesis. The thermal generation of gravitinos after inflation leads to the bound on the reheating temperature, TRH ;S 109 GeV. In this talk we investigate the non-thermal generation of gravitinos, showing that in the early universe it can be extremely efficient and overcome the thermal production by several orders of magnitude. This leads to much tighter constraints on the reheating temperature. |
