论文摘要
我们计算重力生产率，计算其一环热能源。已确定并考虑了通过热切割的自我能力切割而产生的重力生产过程。在先前的计算中纠正分析误差和数值近似值，我们提出了结果。这偏离了最新估计几乎10％。更重要的是，我们提供了一个方便的公式，用于计算重力生产率及其热丰度，这是宇宙加热温度的函数。
We calculate the gravitino production rate, computing its one-loop thermal self-energy. Gravitino production processes that do not result through thermal cuts of its self-energy, have been identified and taken into account. Correcting analytical errors and numerical approximations in the previous calculations, we present our result. This deviates from the latest estimation by almost 10%. More importantly, we provide a convenient formula, for calculating the gravitino production rate and its thermal abundance, as a function of the reheating temperature of the Universe.
