使用$q_T$ -减法对排他性Drell Yan生产进行的混合QCD $\otimes$ QED校正

Mixed QCD$\otimes$QED corrections to exclusive Drell Yan production using the $q_T$-subtraction method

Leandro Cieri, Daniel de Florian, Manuel Der, Javier Mazzitelli

摘要:

在这项工作中,我们扩展的$q_T$ -减法形式,最初开发的QCD修正,混合QCD $\otimes$ QED修正的情况下,并将其应用到完全排他性的计算的${\cal{O}}(α_sα)$的贡献,产生一个离壳层$Z$玻色子的强子碰撞。我们提出了明确的减法项和硬因子的结果,因此提供了所有的成分所需的应用程序的形式主义到${\cal{O}}(α_sα)$。为了研究唯象的影响,我们考虑了离壳层$Z$玻色子衰变为一对中微子,并给出了LHC能区末态轻子的运动学分布。

英文摘要:

In this work we extend the $q_T$-subtraction formalism, originally developed for QCD corrections, to the case of mixed QCD$\otimes$QED corrections, and apply it to the fully exclusive calculation of the ${\cal{O}}(α_sα)$ contribution to the production of an off-shell $Z$ boson in hadronic collisions. We present explicit results for the subtraction term and the hard factor, therefore providing all the ingredients needed for the application of the formalism up to ${\cal{O}}(α_sα)$. To study the phenomenological impact we consider the decay of the off-shell $Z$ boson into a pair of neutrinos, and present kinematical distributions for the final-state leptons at LHC energies.
