Description
This poster presents the measurement of the W boson mass (mW) at the CMS experiment, published in 2024 and representing the most precise determination at the LHC, with an uncertainty of 9.9 MeV. The poster covers some of the most important aspects of the analysis, with a particular focus on the detailed measurement of the muon efficiency scale factors, which play a fundamental role in ensuring good agreement between data and simulation before performing the final fit to mW.
