具有一个重支的双环非平面六盒积分

Two-loop non-planar hexa-box integrals with one massive leg

Adam Kardos, Costas G. Papadopoulos, Alexander V. Smirnov, Nikolaos Syrrakos, Christopher Wever

摘要:

基于简化微分方程方法,我们给出了两圈非平面六盒主积分族的结果。我们引入了一种新的方法来获得边界项,并建立了一个一维的积分表示的主积分的广义多项式,当字母表包含non-factorisable平方根。这些结果对研究与两个强子喷注有关的$W,Z$和Higgs玻色子产生的NNLO QCD修正是有意义的。

英文摘要:

Based on the Simplified Differential Equations approach, we present results for the two-loop non-planar hexa-box families of master integrals. We introduce a new approach to obtain the boundary terms and establish a one-dimensional integral representation of the master integrals in terms of Generalised Polylogarithms, when the alphabet contains non-factorisable square roots. The results are relevant to the study of NNLO QCD corrections for $W,Z$ and Higgs-boson production in association with two hadronic jets.
