Hadronic decay of the gravitino in the early universe and its implications to inflation
arXiv:hep-ph/0410287 · doi:10.1142/9789812701756_0053
Abstract
We discuss the effects of the gravitino on the big-bang nucleosynthesis (BBN), paying particular attention to the hadronic decay mode of the gravitino. We will see that the hadronic decay of the gravitino significantly affect the BBN and, for the case where the hadronic branching ratio is sizable, very stringent upper bound on the reheating temperature after inflation is obtained.
