Title: A precision measurement of the w boson mass at D0

Abstract

I present the first measurement of the W boson mass in the electron decay channel using the Run II D0 detector at the Fermilab Tevatron Collider. The data used was collected from 2002 to 2006 and the integrated luminosity is 1 fb{sup -1}. The W boson mass was determined from the likelihood fit to the measured data distribution. The mass value is found to be 80.401 {+-} 0.023(stat) {+-} 0.037(syst) GeV = 80.401 {+-} 0.044 GeV using the transverse mass spectrum, which is the most precise measurement from one single experiment to date. This result puts tighter constraints on the mass of the standard model Higgs boson. I also present three other measurements that can help to reduce the theoretical uncertainties for the future W mass measurements.
