Abstract

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 root 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/gamma+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 4 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. Differences between inclusive jets and jets from boosted top-quark decays, with and without grooming the soft jet constituents, are also studied.
