Descripción
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→𝜇𝑣 decays, categorized by charge. This novel approach, which incorporates significant in-situ constraints on theoretical inputs and their associated uncertainties and 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.
