TL;DR

This paper reviews measurements of jet-related observables at the LHC, comparing experimental data with theoretical predictions to test perturbative QCD at 7 TeV energy.

Contribution

It provides a comprehensive overview of jet measurements at 7 TeV, including multi-jet rates, shapes, and cross sections, and compares them with models and calculations.

Findings

Data agree with Monte Carlo simulations within uncertainties.

Results test perturbative QCD predictions at high energies.

Jet observables show consistency with theoretical models.

Abstract

During the first years of the LHC operation a large amount of jet data was recorded by the ATLAS and CMS experiments. In this review several measurements of jet-related observables are presented, such as multi-jet rates and cross sections, ratios of jet cross sections, jet shapes and event shape observables. All results presented here are based on jet data collected at a center-of-mass energy of 7 TeV. Data are compared to various Monte Carlo generators, as well as to theoretical next-to-leading-order calculations allowing a test of perturbative Quantum Chromodynamics in a previously unexplored energy region.
