Abstract:
The W boson mass is measured using 13 TeV proton-proton collision data corresponding to an integrated luminosity of 16.8 inverse fb recorded during 2016 by the CMS experiment. The W boson mass is obtained from a fit of the two-dimensional pT - η distribution in a sample of W → μν decays, categorized by charge, yielding one of the most precise measurements of the W mass to date.
