A new approach to compute Feynman Integrals is presented. It relies on an integral representation of a given Feynman Integral in terms of simpler ones. Using this approach, we present, for the first time, results for a certain family of non-planar five-point two-loop Master Integrals with one external off-shell particle, relevant for instance for H + 2 jets production at the LHC, in both Euclidean and physical kinematical regions.

计算费曼积分的内约化方法

提出了一种计算费曼积分的新方法。它依赖于给定 Feynman 积分的积分表示,用更简单的积分表示。使用这种方法,我们第一次展示了具有一个外部壳外粒子的非平面五点双环主积分家族的结果,例如与 LHC 的 H + 2 射流生产相关,在欧几里得和物理运动学区域。
