dc.description.abstractThe 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- k T jets with a jet radius parameter of R jet = 0.4 and in the central jet rapidity region is about 2.5% for transverse momenta ( p T ) of 20  GeV , about 0.5 % for p T = 300   GeV and 0.7 % for p T = 4   TeV . Excellent agreement is found with earlier determinations obtained from p T -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 p T = 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 R jet 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.
