On the thermal regeneration rate for light gravitinos in the early universe
We investigate the light gravitino regeneration rate in the early Universe in models based on N=1 supergravity. Motivated by a recent claim by Fischler, we evaluate finite-temperature effects on the gravitino regeneration rate due to the hot primordial plasma for a wide range of the supersymmetry-br...
