Query: Hadronic decay of the gravitino in the early universe and its
  implications to inflation   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.
