Jet mass scale calibration for large-radius jets and variable-radius jets in ATLAS — •Xuanhong Lou1, Johannes Balz2, and Katharina Behr1 — 1Deutsches Elektronen-Synchrotron, Notkestraße 85, 22607 Hamburg — 2Johannes Gutenberg Universitaet Mainz, Saarstraße 21, 55122 Mainz
Jets are widely used in ATLAS physics analyses and a proper jet calibration is essential in the case of both high-precision measurements of known particles and searches of new physics. During the calibration, the Monte Carlo based correction factors are used to correct, on average, the reconstructed jet properties to particle-level and account for various detector effects. The Jet Mass Scale (JMS) calibration is carefully studied and efforts have been made to improve the mass response closure for groomed large-radius jets and variable-radius jets. A dedicated framework is developed and will be used to derive the official recommendation of calibration factors for the upcoming release 21 analyses.
