Measurement of mass and width of the W boson at LEP
We report on measurements of the mass and total decay width of the W boson with the L3 detector at LEP. W-pair events produced in e +e − interactions between 161 GeV and 183 GeV centre-of-mass energy are selected in a data sample corresponding to a total luminosity of 76.7 pb −1. Combining all final...

Summary: | We report on measurements of the mass and total decay width of the W boson with the L3 detector at LEP. W-pair events produced in e
+e
− interactions between
161
GeV
and
183
GeV
centre-of-mass energy are selected in a data sample corresponding to a total luminosity of 76.7 pb
−1. Combining all final states in W-pair production, the mass and total decay width of the W boson are determined to be
m
W
=80.61±0.15
GeV
and
Γ
W
=1.97±0.38
GeV
, respectively. |
