QCD三阶Drell-Yan产生的双轻子快度分布

Di-lepton Rapidity Distribution in Drell-Yan Production to Third Order in QCD

Xuan Chen, Thomas Gehrmann, Nigel Glover, Alexander Huss, Tong-Zhi Yang, Hua Xing Zhu

摘要:

首次计算了QCD中光子介导的Drell-Yan过程中轻子对快度分布到次-主导阶(N $^3$ LO).该计算基于qT减法,并适当扩展到该量级以用于夸克-反夸克引发的玻恩过程。我们的结果显示了相当大的QCD修正在N $^3$ LO在整个快度区域,并提供了一个完全独立的确认最近的结果,在这个顺序的总Drell-Yan截面。

英文摘要:

We compute for the first time the lepton-pair rapidity distribution in the photon-mediated Drell-Yan process to next-to-next-to-next-to-leading order (N$^3$LO) in QCD. The calculation is based on the qT-subtraction method, suitably extended to this order for quark-antiquark initiated Born processes. Our results display sizeable QCD corrections at N$^3$LO over the full rapidity region and provide a fully independent confirmation of the recent results for the total Drell-Yan cross section at this order.
