Combination of CDF and D0 W-Boson mass measurements

We summarize and combine direct measurements of the mass of the W boson in s√ = 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 me...

Description
Summary:We summarize and combine direct measurements of the mass of the W boson in s√ = 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[superscript −1] of integrated luminosity, and a D0 measurement in the electron channel using data corresponding to 4.3  fb[superscript −1] of integrated luminosity. The resulting Tevatron average for the mass of the W boson is M[subscript W] = 80387 ± 16  MeV. Including measurements obtained in electron-positron collisions at LEP yields the most precise value of M[subscript W] = 80385 ± 15  MeV.
