论文摘要
我们在QCD扰动理论中在近隔至接头到达领先顺序（N3LO）计算出的大型强子对撞机上的Lepton-Neutrino对的生产横截面。我们在此订单下计算虚拟$ w^{\ pm} $ boson的党系数函数。然后，我们使用这些分析功能来研究不同可观察到的扰动序列的进展。特别是，我们研究了新获得的校正对$ W^{\ pm} $玻色子的包含生产横截面的影响，以及$ W^+$，$ W^ - $和/或虚拟光子的生产横截面的比率。最后，我们对LHC的电荷不对称性提出了N3LO预测。
We present the production cross section for a lepton-neutrino pair at the Large Hadron Collider computed at next-to-next-to-next-to leading order (N3LO) in QCD perturbation theory. We compute the partonic coefficient functions of a virtual $W^{\pm}$ boson at this order. We then use these analytic functions to study the progression of the perturbative series in different observables. In particular, we investigate the impact of the newly obtained corrections on the inclusive production cross section of $W^{\pm}$ bosons, as well as on the ratios of the production cross sections for $W^+$, $W^-$ and/or a virtual photon. Finally, we present N3LO predictions for the charge asymmetry at the LHC.
