%T Measurement of the W boson mass with the ALEPH detector
%U https://archiv.ub.uni-heidelberg.de/volltextserver/1941/
%X  The W boson mass has been extracted using W-pairs decaying into evqq and mvqq  final states. The events were selected from the data collected with the ALEPH  detector during the years 1998, 1999 and 2000, corresponding to a total  integrated luminosity of about 650 pb-1. A kinematic fit imposing four-momentum  conservation is then applied to improve the invariant mass resolution. The W  boson mass is obtained from the invariant mass spectrum by a Monte Carlo  reweighting method. Since the statistical and systematical uncertainties are  at the same level, the latter are investigated in great detail. The presented  W boson mass is then included in a preliminary world average which is used to  extract a upper limit on the Higgs boson mass.
