摘要:

本文计算了微扰QCD中Z玻色子产生的截面和微分分布,包括Z玻色子的轻子衰变。我们提出的数值计算结果的横向动量和快度分布的Z玻色子和相关的喷流在大型强子对撞机。我们发现,NNLO修正增加了下一个领先阶(NLO)的预测约1%,并显着降低了尺度变化的不确定性。

英文摘要:

We compute the cross section and differential distributions for the production of a Z boson in association with a hadronic jet to next-to-next-to-leading order (NNLO) in perturbative QCD, including the leptonic decay of the Z boson. We present numerical results for the transverse momentum and rapidity distributions of both the Z boson and the associated jet at the LHC. We find that the NNLO corrections increase the next-to-leading order (NLO) predictions by approximately 1% and significantly reduce the scale variation uncertainty.
