论文摘要
AMFLOW是通过最近提出的辅助质量流量方法来计算尺寸正则化的Feynman积分的Mathematica软件包。在此框架中,积分被视为辅助质量参数的函数,可以通过自动方式构建和求解相对于此参数的差异系统来获得其结果。该软件包的用法通过涉及双盒子家族的明确示例进行了详细描述。
AMFlow is a Mathematica package to numerically compute dimensionally regularized Feynman integrals via the recently proposed auxiliary mass flow method. In this framework, integrals are treated as functions of an auxiliary mass parameter and their results can be obtained by constructing and solving differential systems with respect to this parameter, in an automatic way. The usage of this package is described in detail through an explicit example of double-box family involved in two-loop $t\bar{t}$ hadroproduction.
