Measurement of the W boson mass with the LHCb detector

<!--HTML--><p><span style="color:#000000">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. &nbsp;The W mass is determined from the transverse momentum distribution of muons from W decays.</span><br /> <span style="color:#000000">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.</span></p> Measurement of the W boson mass with the LHCb detector: https://cern.zoom.us/j/67925467279?pwd=Smhjd0FqbVYrRkVKWjBGNXd1M0Nydz09 LHCb seminar 29 juin 2021: https://cern.zoom.us/j/66357161790?pwd=dk5ZS2s5SXZxcUlKOGdKZnV5OHk4QT09
