Sumario: | The quarks and gluons produced in proton-proton collisions form collimated sprays of particles, known as jets. Jets are produced with large cross-sections, and so a precise understanding of the ATLAS detector's response to these objects improves the quality of physics analyses. The Jet Energy Scale (JES) is studied in situ by several analyses which are inputs to a statistical combination. The absolute JES is measured using events where the jet recoils against a reference object, which can be a calibrated photon, a reconstructed $Z$ boson, or a system of well-measured jets with lower $p_{\mathrm{T}}$. The relative scale of jets in the forward and central detector regions is measured using balanced dijet systems. Separate measurements and combinations are performed for jets reconstructed from topological clusters and particle-flow objects. This poster presents the latest measurements of the JES in $13$ TeV $pp$ data. |
