TL;DR
This paper reports measurements of jet cross sections in deep-inelastic scattering at HERA, testing QCD predictions, probing the proton's gluon distribution, and extracting the strong coupling constant with high precision.
Contribution
It provides comprehensive experimental data that validate NLO QCD calculations and offers new precise measurements of the strong coupling constant.
Findings
Jet cross sections agree with NLO QCD predictions
Gluon distribution in the proton is consistent with previous extractions
Precise values of the strong coupling constant are obtained
Abstract
Jet cross sections in deep-inelastic scattering over a wide region of phase space have been measured at HERA. These cross section measurements provide a thorough test of the implementation of Quantum Chromodynamics in next-to-leading order (NLO) calculations. They also provide the opportunity to test the consistency of the gluon distribution in the proton as extracted from (mainly) inclusive DIS measurements. Comparison of the cross sections with NLO enables accurate extractions of the strong coupling constant, , to be made, several of which are reported here.
