Combination of CDF and D0 W-Boson mass measurements

Abstract: We summarize and combine direct measurements of the mass of the W boson in ffiffi s p ¼ 1:96 TeV proton-antiproton collision data collected by CDF and D0 experiments at the Fermilab Tevatron Collider. Earlier measurements from CDF and D0 are combined with the two latest, more precise measurements: a CDF measurement in the electron and muon channels using data corresponding to 2:2 fb 1 of integrated luminosity, and a D0 measurement in the electron channel using data corresponding to 4:3 fb 1 of integrated luminosity. The resulting Tevatron average for the mass of the W boson is MW ¼ 80387 16 MeV. Including measurements obtained in electron-positron collisions at LEP yields the most precise value of MW ¼ 80385 15 MeV.
