Description

Abstract:

The W boson mass is measured using proton-proton collision data with an integrated luminosity of 16.8 fb⁻¹, collected by the CMS experiment in 2016. The mass is extracted through a fit to a highly granular two-dimensional distribution of transverse momentum (pT) and pseudorapidity (η) in a sample of W→μν decays, categorized by charge. This novel approach, which incorporates significant in-situ constraints on theoretical inputs and their associated uncertainties, along with precise determinations of experimental effects, yields a highly accurate W boson mass measurement of 80,360.2 ± 9.9 MeV, consistent with the Standard Model prediction.
