Abstract

A measurement of the W boson mass using 4.3 fb^-1 of integrated luminosity collected with the D0 detector during Run II of the Fermilab Tevatron collider is presented. Based on a sample of 1.68 * 10⁶ W->enu candidate events, the W boson mass is measured to be M_W = 80.367 +/- 0.026 GeV. Combining this result with an earlier D0 result determined using an independent Run II data sample of 1 fb^-1 of integrated luminosity, yields M_W = 80.375 +/- 0.023 GeV.
