CERN-LHC. This paper presents cross sections for the production of a W boson in association with jets, measured in proton--proton collisions at sqrt(s)=7 TeV with the ATLAS experiment at the Large Hadron Collider. With an integrated luminosity of 4.6 fb^{-1}, this data set allows for an exploration of a large kinematic range, including jet production up to a transverse momentum of 1 TeV and multiplicities up to seven associated jets. The production cross sections for W bosons are measured in both the electron and muon decay channels. Differential cross sections for many observables are also presented including measurements of the jet observables such as the rapidities and the transverse momenta as well as measurements of event observables such as the scalar sums of the transverse momenta of the jets. The measurements are compared to numerous QCD predictions including next-to-leading-order perturbative calculations, resummation calculations and Monte Carlo generators Note added (27 OCT 2015): The bin ranges in the DeltaPhi table were incorrectly rounded. This has been fixed.

欧洲核子研究中心-大型强子对撞机(CERN-LHC):本论文报道了在大型强子对撞机(Large Hadron Collider)ATLAS实验中,于质心系能量√s=7 TeV的质子-质子碰撞环境下测得的W玻色子(W boson)伴随喷注(jet)产生的截面。该数据集的积分亮度(integrated luminosity)为4.6 fb⁻¹,可用于探索宽广的运动学范围,涵盖横动量(transverse momentum)最高达1 TeV的喷注产生,以及伴随喷注数目最多为7个的事件。W玻色子的产生截面分别在电子衰变道和μ子(muon)衰变道中完成测量。本文还报道了多个可观测量(observables)的微分截面(differential cross sections),其中包括喷注快度(rapidity)和横动量等喷注重观测量,以及喷注横动量标量和等事件观测量的测量结果。本次测量结果与诸多量子色动力学(QCD)预言进行了对比,其中包括次领头阶微扰计算、重整化求和计算以及蒙特卡洛(Monte Carlo)事件产生器。 补充说明(2015年10月27日):ΔΦ(DeltaPhi)分布表中的分箱范围曾被错误修约,现已修正。
