Description

We study at a quantitative level the impact of the uncertainties on the value of the W boson mass measured at hadron colliders due to the proton parton distribution functions (PDFs). The value of the W boson mass is extracted, by means of a template fit technique, from the lepton-pair transverse mass distribution measured in the charged current Drell-Yan process.. We conclude that PDF uncertainties do not challenge a measurement of the W boson mass at the level of 20 MeV accuracy. We discuss the prospects to improve on this accuracy with available and future data from the LHC.
