NNLO QCD中的Drell-Yan过程

The Drell-Yan process in NNLO QCD

M. Grazzini

摘要:

我们考虑强子碰撞中W和Z玻色子的产生。我们提出了一个选择的数值计算结果,通过一个完全排他性的计算,以次到次到主导阶(NNLO)在QCD微扰理论。我们包括了$γ$ - $Z$干涉、有限宽度效应、矢量玻色子的轻子衰变和相应的自旋关联。计算是完全现实的,因为它允许我们对末态轻子和相关的部分子应用任意的运动学切割,并以bin直方图的形式计算相应的分布。

英文摘要:

We consider the production of W and Z bosons in hadron collisions. We present a selection of numerical results obtained through a fully exclusive calculation up to next-to-next-to-leading order (NNLO) in QCD perturbation theory. We include the $γ$--$Z$ interference, finite-width effects, the leptonic decay of the vector bosons and the corresponding spin correlations. The calculation is completely realistic, since it allows us to apply arbitrary kinematical cuts on the final-state leptons and the associated partons, and to compute the corresponding distributions in the form of bin histograms.
