摘要:

本文测量了μ子衰变道中喷注产生的W玻色子的微分截面。测量是基于13 TeV的质子-质子碰撞数据对应的积分亮度的2.2个反femtobarns,记录的CMS检测器在大型强子对撞机。的截面报告作为功能的喷流多重性,喷流横向动量PT,喷流快度,喷流的标量PT总和,和角之间的相关性μ子和不同的喷流多重性。测得的截面与预测,包括多腿领先阶(LO)和下一个LO矩阵元计算接口的部分子淋浴,以及一个下一个下一个LO计算的W玻色子和一个喷气生产。

英文摘要:

A measurement of the differential cross sections for a W boson produced in association with jets in the muon decay channel is presented. The measurement is based on 13 TeV proton-proton collision data corresponding to an integrated luminosity of 2.2 inverse femtobarns, recorded by the CMS detector at the LHC. The cross sections are reported as functions of jet multiplicity, jet transverse momentum pT, jet rapidity, the scalar pT sum of the jets, and angular correlations between the muon and the jet for different jet multiplicities. The measured cross sections are in agreement with predictions that include multileg leading-order (LO) and next-to-LO matrix element calculations interfaced with parton showers, as well as a next-to-next-to-LO calculation for the W boson and one jet production.
