利用辅助质量流自动计算含线性传播子的Feynman积分

Automatic computation of Feynman integrals containing linear propagators via auxiliary mass flow

Zhi-Feng Liu, Yan-Qing Ma

摘要:

我们提出了一个配方,系统地计算费曼积分包含线性传播子使用辅助质量流方法。该方法的关键是为每个线性传播子引入一个二次项,然后使用微分方程来消除它们的影响。作为应用,我们计算了含有一个规范环的真空积分的所有主积分,并用非平凡的维数递推关系检验了结果。

英文摘要:

We proposed a recipe to systematically calculate Feynman integrals containing linear propagators using the auxiliary mass flow method. The key of the recipe is to introduce a quadratic term for each linear propagator and then using differential equations to get rid of their effects. As an application, we calculated all master integrals of vacuum integrals containing a gauge link up to four loops, and we checked the results by nontrivial dimensional recurrence relations.
