In situ measurements of the ATLAS jet energy resolution using 13 TeV pp data

The hadronization of quarks and gluons to form jets is a complex process, and the subsequent interaction with the detector is non-trivial. However, the abundance of jets makes it very important to understand the typical range of energy values that a given jet can deposit in the detector, which quant...

description The hadronization of quarks and gluons to form jets is a complex process, and the subsequent interaction with the detector is non-trivial. However, the abundance of jets makes it very important to understand the typical range of energy values that a given jet can deposit in the detector, which quantifies the experimental energy resolution. The Jet Energy Resolution (JER) is studied in situ by two analyses which are then inputs to a statistical combination. The first analysis measures the effect of detector and pile-up noise on the JER, which dominate this quantity at low pT. The second measures the JER of anti-kt R=0.4 jets with pT up to 1.5 TeV using well-balanced dijet systems. Separate measurements and combinations are performed for jets reconstructed from topological clusters and particle-flow objects. This poster presents the first measurement of the JER in 13 TeV pp data.
