Two-loop mixed QCD-EW corrections to neutral current Drell-Yan

Tommaso Armadillo, Roberto Bonciani, Simone Devoto, Narayan Rana, Alessandro Vicini

摘要:

本文给出了中性流Drell-Yan过程的两圈混合强弱电虚修正,并在辅助文件中给出了减去红外线的有限余项的显式公式。末态共线奇点由轻子质量正则化。所有相关的费曼积分的评估,包括那些多达两个内部的质量线,已经制定了依赖于分析和半分析技术,在复值质量的情况下。

英文摘要:

We present the two-loop mixed strong-electroweak virtual corrections to the neutral current Drell-Yan process and we provide, in ancillary files, the explicit formulae of the infrared-subtracted finite remainder. 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 internal massive lines, has been worked out relying on analytical and semi-analytical techniques, in the case of complex-valued masses.
