计算多个费曼图的不变振幅平方的Mathematica软件

A Mathematica Program for Calculating Multiple Feynman Diagrams With Invariable Squared Amplitudes

利用Mathematica符号处理系统,发展了一种用于直接计算多个费曼图不变振幅平方的软件。利用该软件,用户仅需要根据费曼规则,输入所有有贡献的图的振幅,即可求出粒子过程的不变振幅平方。

A Mathematica program is introduced. Users of the program will only need to feed in the amplitudes of all the contributing diagrams according to the Feynman rule to obtain the invariable squared amplitudes of the particle reaction process.
