The W boson mass is measured using proton-proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 1.6 fb-1 recorded during 2016 by the LHCb experiment. The W mass is determined from the transverse momentum distribution of muons from W decays.

This analysis serves as pathfinder for future exploitation, with larger datasets, of LHCb's unique forward rapidity coverage to complement measurements of the W mass by the other LHC experiments. The result is compared with previous measurements of the W mass and with the predicted value from the global electroweak fit.
