论文摘要
Geant4中的抗蛋白（$ \ bar {p} $）的发电机是使用理论模型开发的，考虑到近阈值处理，并在彗星实验中先使用。通过与Cern（1970）和Itep（1994）中取得的实验结果进行比较，已经验证了该发电机的精度。通过将此发电机实施到彗星的官方数据分析框架中，可以正确评估彗星实验中$ \ bar {p} $的产量。由$ \ bar {p} $引起的背景也可以在将来由该生成器估算，这将指导设计和优化。此外，该发电机也可以用于模拟其他涉及接近阈值$ \ bar {p} $ generation的实验。
A generator of antiproton ($\bar{p}$) in Geant4 has been developed using a theoretical model with the consideration of near-threshold treatment and used preliminarily in COMET experiment. The precision of this generator has been verified by comparing with experimental results taken in CERN (1970) and ITEP (1994). By implementing this generator into official data analysis framework of COMET, the yield of $\bar{p}$ in COMET experiment can be evaluated properly. Background caused by $\bar{p}$ can also be estimated by this generator in future, which will instruct the design and optimization. Moreover, this generator can also be used in the simulation of other experiments involving near-threshold $\bar{p}$ generation.
