Muon Momentum Scale and Resolution Calibration for CMS — •Dorian Guthmann, Markus Klute, and Jost von den Driesch — Karlsruher Institut für Technologie, Karlsruhe, Deutschland

Many analyses conducted with the CMS experiment at the LHC rely on a precise description of muon momenta. However, deviations between data and simulation arise due to mismodeling of the detector, such as misalignment and limited magnetic field precision. To address this, scale and resolution corrections are applied to the transverse momentum of muons, mitigating biases and aligning the theoretical description of muons with their experimental counterpart. This presentation will provide an overview of the progress made over the past year in refining and enhancing these corrections.
