W mass measurements using fully hadronic events at LEP2
Since 1996 each LEP experiment recorded data corresponding to an integrated luminosity around 460-500 pb/sup -1/ at centre-of-mass energies between 161 GeV and 202 GeV. The experimental methods to measure the mass of the W boson in the fully hadronic channel are discussed and the preliminary combine...

| description | Since 1996 each LEP experiment recorded data corresponding to an integrated luminosity around 460-500 pb/sup -1/ at centre-of-mass energies between 161 GeV and 202 GeV. The experimental methods to measure the mass of the W boson in the fully hadronic channel are discussed and the preliminary combined value of the four LEP experiments is presented M/sub W/(qqqq) = 80 432 +or- 0 073 GeV. The LEP combined result for the mass of the W boson, obtained from all channels and all data recorded at centre-of-mass energies above the W- pair threshold, is M/sub W/ = 80 427 +or- 0 046 GeV. The width of the W boson is measured to be Gamma /sub W/ = 2 12 +or- 0 11 GeV.. |
