我们讨论了引力子对大爆炸核合成（BBN）的影响，特别注意引力子的强子衰变模式。我们将看到，强子衰变的引力子显着影响的BBN和的情况下，强子分支比是相当大的，非常严格的上限后，暴胀后的再加热温度。
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.
