Updated jet energy scale calibration using Monte Carlo samples for ATLAS — •Gediminas Glemža and Christian Sander — DESY, Notkestr. 85, 22607 Hamburg, Germany
An updated simulation-based jet energy scale calibration utilising the newest ATLAS software release version and updated Run-2 Monte Carlo samples is presented. The calibration restores the jet energy scale back to particle level jets. The jets are reconstructed using particle-flow objects and clustered using the anti-kt jet algorithm with a radius parameter of 0.4. The presented calibration accounts for in-time and out-of-time residual pile-up effects, calibrates the absolute jet energy scale and pseudorapidity, as well as provides additional corrections based on global jet observables. The presented procedure is based on similar simulation-based calibrations carried out during the period of Run-2 and their performance comparison is discussed.
