一维正则化中单圈水平计算紫外发散部分的递推方法

A Recursive Method to Calculate UV-divergent Parts at One-Loop Level in Dimensional Regularization

Feng Feng

摘要:

介绍了一种在一维正则化中计算单圈水平上的紫外发散部分的方法。该方法以递推为基础,基本积分为递推约化后的无标度积分,除环动量本身外不涉及其他动量标度。该方法可以很容易地实现在任何符号计算机语言,并在Mathematica的实现是准备使用。

英文摘要:

A method is introduced to calculate the UV-divergent parts at one-loop level in dimensional regularization. The method is based on the recursion, and the basic integrals are just the scaleless integrals after the recursive reduction, which involve no other momentum scales except the loop momentum itself. The method can be easily implemented in any symbolic computer language, and an implementation in Mathematica is ready to use.
