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-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/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 p(T) = 300 GeVand 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. |
