  "description": "<p>The response of the ATLAS detector to large-radius jets is measured in situ using 36.2 fb  ${}^{-1}$  of   $\\sqrt{s}=13$  TeV proton\u2013proton collisions provided by the LHC and recorded by the ATLAS experiment during 2015 and 2016. The jet energy scale is measured in events where the jet recoils against a reference object, which can be either a calibrated photon, a reconstructed Z boson, or a system of well-measured small-radius jets. The jet energy resolution and a calibration of forward jets are derived using dijet balance measurements. The jet mass response is measured with two methods: using mass peaks formed by W bosons and top quarks with large transverse momenta and by comparing the jet mass measured using the energy deposited in the calorimeter with that using the momenta of charged-particle tracks. The transverse momentum and mass responses in simulations are found to be about 2\u20133% higher than in data. This difference is adjusted for with a correction factor. The results of the different methods are combined to yield a calibration over a large range of transverse momenta   $\\left({p}_{T}\\right)$ . The precision of the relative jet energy scale is 1\u20132% for   $200\\phantom{\\rule{3.33333pt}{0ex}}\\text{GeV}\\phantom{\\rule{3.33333pt}{0ex}}&lt;\\phantom{\\rule{3.33333pt}{0ex}}{p}_{T}\\phantom{\\rule{3.33333pt}{0ex}}&lt;\\phantom{\\rule{3.33333pt}{0ex}}2\\phantom{\\rule{3.33333pt}{0ex}}\\text{TeV}$ , while that of the mass scale is 2\u201310%. The ratio of the energy resolutions in data and simulation is measured to a precision of 10\u201315% over the same   ${p}_{T}$  range.</p>",
