The calibration of large-radius jets using the Run 2 dataset with the ATLAS detector
ATLAS Collaboration
Abstract
The ATLAS experiment has developed an extensive procedure based on Monte Carlo simulation and collision data to calibrate the response of large-radius jets. This paper describes the Run 2 calibration of large-radius jets reconstructed from Unified Flow Objects and groomed with the Soft Drop algorithm, using data produced in proton-proton collisions at s=13 TeV. Results are presented for the Monte Carlo-based correction and for the in situ methods that are used to validate the jet energy and mass scales and their resolutions in collision data. The residual uncertainty on the jet energy and mass scales is close to 1% for transverse momenta up to 1 TeV and is 2-3% up to 2 TeV, enabling sensitive searches to beyond the Standard Model particles and precise Standard Model measurements with boosted objects.
