混合QCD $\otimes$ QED对LHC上壳层$Z$玻色子产生的修正

Mixed QCD$\otimes$QED corrections to on-shell $Z$ boson production at the LHC

Maximilian Delto, Matthieu Jaquier, Kirill Melnikov, Raoul Röntsch

摘要:

我们计算了LHC在完全排他水平上产生壳层上$Z$玻色子的混合QCD $\otimes$ QED修正。我们还包括了对$Z$玻色子产生的因子化NLO QCD修正和对$Z$玻色子衰变为两个轻子的NLO QED修正。我们利用一个abelianised版本的嵌套软共线减法形式主义来执行此计算。我们研究了混合QCD $\otimes$ QED修正对LHC现象学相关观测量的唯象影响。

英文摘要:

We compute the mixed QCD$\otimes$QED corrections to the production of on-shell $Z$ bosons at the LHC at a fully-exclusive level. We also include the factorised NLO QCD correction to $Z$ boson production and NLO QED correction to $Z$ boson decay into two leptons. We make use of an abelianised version of the nested soft-collinear subtraction formalism to perform this computation. We study the phenomenological impact of the mixed QCD$\otimes$QED corrections for a number of observables relevant for LHC phenomenology.
