Contribution

It provides detailed distributions of topological observables in multi-jet events and assesses the performance of various event generators, highlighting MADGRAPH+PYTHIA6 as the most accurate.

Findings

MADGRAPH+PYTHIA6 best matches the data

Distributions corrected for detector effects

Provides insights into multi-jet event modeling

Abstract

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.
