标题： Two-loop mixed QCD-EW corrections to charged current Drell-Yan

摘要： 我们给出了带电电流Drell-Yan过程的两圈混合强电弱虚修正。末态的.collinear奇异性通过轻子质量来正则化。所有相关的费曼积分的计算，包括那些具有最多两条不同内部大质量线的积分，都是基于半解析技术，并使用复数值质量完成的。我们可以提供，在任意相空间点处，以.$W$-玻色子质量展开的解，围绕一个参考值。从这些展开式开始，我们可以以可忽略的时间，在它们收敛半径内，为任意.$W$-玻色子质量准备一个数值网格。 显示英文摘要

摘要： We present the two-loop mixed strong-electroweak virtual corrections to the charged current Drell-Yan process. The final-state collinear singularities are regularised by the lepton mass. The evaluation of all the relevant Feynman integrals, including those with up to two different internal massive lines, has been worked out relying on semi-analytical techniques, using complex-valued masses. We can provide, at any arbitrary phase-space point, the solution as a power series in the $W$-boson mass, around a reference value. Starting from these expansions, we can prepare a numerical grid for any value of the $W$-boson mass within their radius of convergence in a negligible amount of time.
