摘要： 利用Mathematica符号处理系统,发展了一种用于计算可重整规范理论的单圈费曼图振幅的软件-MATHELDCA。利用该软件,用户仅需要根据费曼规则输入所贡献的费曼图振幅,即可以对粒子过程的辐射修正进行计算。
关键词: Mathematica符号处理系统, 单圈费曼图振幅, 辐射修正, 求阵迹
Abstract: Using Mathematica symbalic manipulation system, the computer program MATHELDCA is developed for calculating one loop Feynman diagrams in renormalizable gauge theories. It is only needed to input the amplitudes of contributed diagrams according to the Feynman rule, so as to calculate the radiative corrections of particle process.
Key words: Mathematica symbalic manipulation system, amplitude of one loop feynman diagram, radiative corections, calculating trace
