Abstract
Jets are commonly produced in heavy-ion collisions at the LHC energies. Their calibration is essential for precise measurements of various processes, such as top-quark pair production. The report presents the measurement of jet energy scale and resolution in proton-lead collisions collected at 8.16 TeV in 2016 by the ATLAS experiment. The method involving the balance between $Z$ boson and jet transverse momenta is used for jet $p_\mathrm{T}> 20\;\mathrm{GeV}$ and $|\eta|<2.5$ to estimate jet performance in both data and Monte Carlo simulation. The performance of two jet definitions, referred to as PFlow and HI jets, is evaluated and results are compared including systematic uncertainties. The results of these studies are a key input to the ongoing analysis of top-quark pair production in p+Pb collisions.
