论文摘要
我们向中性电流drell-yan流程$（q \ bar {q} \ rightArrow l^+ l^ - ）$展示了两个循环混合QCD-QED虚拟校正所需的主积分的计算。在建立了51个主积分的基础之后，我们使用Magnus算法将后者投入到规范的形式中。然后扩大对Lepton质量的依赖性，以使潜在的大对数贡献得到保留。在确定所有边界常数之后，我们将泰勒级数的系数围绕四个时空维度，以四个时空的尺寸为四。
We showcase the calculation of the master integrals needed for the two loop mixed QCD-QED virtual corrections to the neutral current Drell-Yan process $(q\bar{q}\rightarrow l^+ l^-)$. After establishing a basis of 51 master integrals, we cast the latter into canonical form by using the Magnus algorithm. The dependence on the lepton mass is then expanded such that potentially large logarithmic contributions are kept. After determining all boundary constants, we give the coefficients of the Taylor series around four space-time dimensions in terms of generalized polylogarithms up to weight four.
