W mass at LEP2

Recent studies to finalize the systematic error estimates on the measurement of the mass of the W boson at LEP2 are reviewed. Results including a new preliminary value from Aleph are updated together with the world average which is now 80.426 +- 0.034GeV/c2. The updated electroweak fit gives a 95% C...

Sumario:Recent studies to finalize the systematic error estimates on the measurement of the mass of the W boson at LEP2 are reviewed. Results including a new preliminary value from Aleph are updated together with the world average which is now 80.426 +- 0.034GeV/c2. The updated electroweak fit gives a 95% C.L. upper limit on the mass of the Higgs boson of 211GeV/c2.
