| 摘 要： | 在高能物理中，经常遇到费曼图的振幅解析计算的问题，而其中的求迹运算是困扰理论物理工作者的一个难点，尤其当相关图较多或者被求迹的γ矩阵在六个以上的时候：分析了近年来相应的高能物理计算工具FeynCalc，介绍了它的工作环境和操作方法，并用它对γγ→e^＋e^-过程进行了相应的求迹运算，其解析结果与手工推导结果是一致的，

| Abstract: | The analytical calculations of Feynman diagram amplitude are the problems that are always encountered in High Energy Physics; the evaluation of trace operation is a complex problem to theoretical physicists. The problem is more complex either with more Feynman diagrams or number of γ matrixes over 6. In this paper, FeynCalc tools were introduced which have been developed in recent years of high-energy physics. The work environment of FeynCalc and its operation method were presented here. Then a practical process of γγ→e^＋e^- trace operation is evaluated based on FeynCalc, the analytical output is consistent with the manual derivation. |
