Název v původním jazyce

A precise measurement of the jet energy scale derived from single-particle measurements and in situ techniques in proton-proton collisions at √s ​= 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

The jet energy calibration and its uncertainties are derived from measurements of the calorimeter response to single particles in both data and Monte Carlo simulation using proton-proton collisions at √s ​=13 TeV collected with the ATLAS detector during Run 2 at the Large Hadron Collider. The jet calibration uncertainty for anti-kt​ jets with a jet radius parameter of Rjet=0.4 and in the central jet rapidity region is about 2.5% for transverse momenta (pT​) of 20 GeV, about 0.5% for pT=300 GeV and 0.7% for pT=4 TeV. Excellent agreement is found with earlier determinations obtained from pT​-balance based in situ methods (Z/γ+jets). The combination of these two independent methods results in the most precise jet energy measurement achieved so far with the ATLAS detector with a relative uncertainty of 0.3% at pT=300 GeV and 0.6% at 44 TeV. The jet energy calibration is also derived with the single-particle calorimeter response measurements separately for quark- and gluon-induced jets and furthermore for jets with Rjet varying from 0.2 to 1.0 retaining the correlations between these measurements.
