CERN-LHC. Differential cross sections for a W boson produced in association with jets are measured in a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV recorded with the CMS detector and corresponding to an integrated luminosity of 2.2 inverse femtobarns. The W bosons are identified through their decay into a muon and a neutrino. The cross sections are reported as functions of jet multiplicity, jet transverse momenta, jet rapidity, the scalar sum of jet transverse momenta (HT), and angular correlations between the muon and each jet for different jet multiplicities. The cross sections are measured in the fiducial region defined by a muon with pT > 25 GeV and pseudorapidity |eta| < 2.4, and by a transverse mass between the muon and the missing transverse energy MT > 50 GeV. Jets are reconstructed using the anti-kT algorithm with a distance parameter R = 0.4, and only jets with pT > 30 GeV, rapidity |y| < 2.4, and a separation of deltaR > 0.4 from the muon are considered. In addition, the differential cross section is measured as a function of the angular distance (DeltaR) between the muon and the closest jet for events with one or more jets, requiring jets with pT > 100 GeV and the leading jet with pT > 300 GeV.

欧洲核子研究中心大型强子对撞机(CERN-LHC)数据集:本实验测量了质子-质子碰撞中伴随喷注(jet)产生的W玻色子(W boson)的微分截面。实验数据取自质心系能量为13 TeV的质子-质子碰撞样本,由CMS探测器(Compact Muon Solenoid detector)采集,对应积分亮度为2.2 飞靶⁻¹。W玻色子通过衰变为缪子(muon)和中微子(neutrino)的过程进行识别。该微分截面以喷注多重数(jet multiplicity)、喷注横向动量(transverse momentum, p_T)、喷注快度(jet rapidity)、喷注横向动量标量和(HT),以及不同喷注多重数下缪子与各喷注间的角关联作为观测变量进行报道。微分截面的测量限定于以下fiducial区域(fiducial region):缪子横向动量p_T > 25 GeV、赝快度(pseudorapidity, |η|)< 2.4,且缪子与缺失横向能量(missing transverse energy)构成的横向质量(transverse mass, M_T)> 50 GeV。喷注采用距离参数R=0.4的anti-kT算法进行重建,仅考虑满足以下条件的喷注:横向动量p_T > 30 GeV、快度|y| < 2.4,且与缪子的角距离ΔR > 0.4。此外,针对包含至少一个喷注的事件,本实验还测量了以缪子与最近喷注间的角距离ΔR为变量的微分截面,其中要求喷注横向动量p_T > 100 GeV,且领头喷注(leading jet)横向动量p_T > 300 GeV。
