sqrt(s)= 7 TeV pp碰撞中包含三喷流和四喷流事件的拓扑观测量分布

Distributions of topological observables in inclusive three- and four-jet events in pp collisions at sqrt(s) = 7 TeV

CMS Collaboration

摘要:

本文介绍了拓扑观测量的分布在包容性的三个和四个喷流事件产生的pp碰撞在质心能量为7 TeV的CMS实验收集的数据样本对应于5.1个反femtobarns的光度。对这些分布进行了检测器效应的校正,并与基于领先阶的两部分子和多部分子矩阵元素的几种事件发生器进行了比较。在所考虑的计算中,与PYTHIA 6接口的MADGRAPH显示出与数据的最佳总体一致性。

英文摘要:

This paper presents distributions of topological observables in inclusive three- and four-jet events produced in pp collisions at a centre-of-mass energy of 7 TeV with a data sample collected by the CMS experiment corresponding to a luminosity of 5.1 inverse femtobarns. The distributions are corrected for detector effects, and compared with several event generators based on two- and multi-parton matrix elements at leading order. Among the considered calculations, MADGRAPH interfaced with PYTHIA6 displays the best overall agreement with data.
