An innovative approach is used to correct for potential charge-dependent momentum biases related to the knowledge of the detector geometry, using the Z? ?+?- resonance. The muon momentum scale and resolution are measured using samples of J/ ?? ?+?- and Z? ?+?- events. A calibration procedure is defined and applied to simulated data to match the performance measured in real data. The calibration is validated using an independent sample of ? ? ?+?- events. At the Z (J/ ?) peak, the momentum scale is measured with an uncertainty at the 0.05% (0.1%) level, and the resolution is measured with an uncertainty at the 1.5% (2%) level. The charge-dependent bias is removed with a dedicated in situ correction for momenta up to 450 GeV with a precision better than 0.03 TeV - 1 . © 2023, The Author(s).eninfo:eu-repo/semantics/openAccessCalibrationCharged ParticlesGermanium CompoundsTellurium CompoundsAtlas DetectorsCalibration ProcedureData SampleDetector GeometryInnovative ApproachesIntegrated LuminosityPerformancePerformance StudyPotential ChargeUncertaintyMomentumArticle8382-s2.0-8517975682310.1140/epjc/s10052-023-11584-xN/A
