Measurement of the mass of the W boson using direct reconstruction at
root s=183 GeV

Αγγλικά

From data corresponding to an integrated luminosity of 53.5 pb(-1) taken
during the 183 GeV run in 1997, DELPHI has measured the W mass from
direct reconstruction of WW –> l<(nu)over bar>q (q) over bar and WW –>
q (q) over bar q (q) over bar events. Combining these channels, a value
of m(w) = 80.238 +/- 0.154(stat) +/- 0.035(syst) +/- 0.035(fsi) +/-
0.021 (LEP) GeV/c(2) is obtained, where fsi denotes final state
interaction.
Combined with the W mass obtained by DELPHI from the WW production
cross-section and with the direct measurement at 172 GeV this leads to a
measured value of m(w) = 80.270 +/- 0.137(stat) +/- 0.031(syst) +/-
0.030(fsi) +/- 0.021(LEP)GeV/c(2), in good agreement with the Standard
Model expectation.
The width of the W boson is also measured, giving the value Gamma(W) =
2.48 +/- 0.40(stat) +/- 0.10(syst)GeV/c(2). (C) 1999 Elsevier Science
