"Table 14" of "Measurements of the W production cross sections in association with jets with the ATLAS detector"
收藏资源简介:
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)。本文报道了大型强子对撞机ATLAS实验在质心系能量√s=7 TeV的质子-质子碰撞中,测得的伴随喷注(jet)产生W玻色子(W boson)的产生截面。该数据集的积分亮度为4.6 fb⁻¹,可覆盖广阔的运动学范围,包括横向动量最高达1 TeV的喷注产生,以及最多伴随7个喷注的事例。W玻色子的产生截面分别在电子衰变道和μ子衰变道中完成测量。本文同时报道了多类可观测量的微分截面,涵盖喷注快度、横向动量等喷注级可观测量,以及喷注横向动量标量和等事例级可观测量的测量结果。将本次测量结果与众多量子色动力学(QCD)理论预言进行了比对,包括次领头阶微扰计算结果、重整化求和计算结果以及蒙特卡洛(Monte Carlo)发生器预言。2015年10月27日补充说明:Δφ分布表中的区间范围曾存在舍入错误,现已修正。
