Measurement of the mass of the W boson using direct reconstruction at root s=183 GeV
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 → ℓv̄qq̄ and WW → qq̄qq̄ events. Combining these channels, a value of mw = 80.238 ± 0.154(stat) ± 0.035(syst) ± 0.035(fsi) + 0.021(LE...

description | 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 → ℓv̄qq̄ and WW → qq̄qq̄ events. Combining these channels, a value of mw = 80.238 ± 0.154(stat) ± 0.035(syst) ± 0.035(fsi) + 0.021(LEP)GeV/c2 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 mw = 80.270 ± 0.137(stat) ± 0.031(syst) ± 0.030(fsi) ± 0.021(LEP)GeV/c2, in good agreement with the Standard Model expectation. The width of the W boson is also measured, giving the value Γw= 2.48 ± 0.40(stat) ± 0.10(syst)GeV/c2. © 1999 Elsevier Science B.V. All rights reserved. |
