摘要:

基于[K.~]中发展的方法,H.~ Phan和T.~ Riemann,Phys. Lett. B {\bf 791}(2019)257],本文给出了一般$d$-维中标量单圈二、三、四点积分的详细解析结果.计算考虑了所有外部运动学配置和内部质量分配。解析公式用Gauss $_2F_1$、Appell $F_1$和Lauricella $F_S$函数等广义超几何级数表示。

英文摘要:

Based on the method developed in [K.~H.~Phan and T.~Riemann, Phys.\ Lett.\ B {\bf 791} (2019) 257], detailed analytic results for scalar one-loop two-, three-, four-point integrals in general $d$-dimension are presented in this paper. The calculations are considered all external kinematic configurations and internal mass assignments. Analytic formulas are expressed in terms of generalized hypergeometric series such as Gauss $_2F_1$, Appell $F_1$ and Lauricella $F_S$ functions.
