论文摘要
我们向中性当前的drell-yan过程介绍了两环混合的强链式虚拟校正,并在辅助文件中提供了剩余的剩余剩余的有限余量的明确公式。最终的州共线奇异性是Lepton Mass正规的。在复杂价值的质量的情况下,对所有相关的Feynman积分进行了评估,包括最多两条内部质量线的那些依赖分析和半分析技术的评估。
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.
