论文摘要
我们将$ {\ cal o}(αα_s)$校正的第一个分析结果介绍给总横截面,用于在HADRON COLLIDERS上包含壳$ Z $ BOSON。我们包括一组完整的贡献,具有光子和巨大的弱凸效效应,这些效应已以分析形式计算,并以多组含量和椭圆形积分表示。我们提出数值结果,与LHC的精确研究有关。这些校正提高了预测的准确性,并有助于降低理论不确定性的QCD成分。
We present the first analytical results for the ${\cal O}(αα_s)$ corrections to the total cross section for the inclusive production of an on-shell $Z$ boson at hadron colliders. We include the complete set of contributions, with photonic and massive weak gauge boson effects, which have been computed in analytical form and expressed in terms of polylogarithmic and elliptic integrals. We present numerical results, relevant for the precision studies at the LHC. These corrections increase the accuracy of the predictions and contribute to the reduction of the QCD component of the theoretical uncertainty.
