at root s=161-209 GeV

Περίληψη:
A measurement of the W boson mass and width has been performed by the
DELPHI collaboration using the data collected during the full LEP2
programme (1996-2000). The data sample has an integrated luminosity of
660 pb(-1) and was collected over a range of centre-of-mass energies
from 161 to 209 GeV.
Results are obtained by applying the method of direct reconstruction of
the mass of the W from its decay products in both the W+W- -> l (nu)
over bar (l) and W+W- -> q (q) over bar’(q) over barq’channels. The W
mass result for the combined data set is
M-W = 80.336 +/- 0.055(Stat.) +/- 0.028(Syst.) +/- 0.025(FSI) +/-
0.009(LEP) GeV/c(2) ,
where FSI represents the uncertainty due to final state interaction
effects in the q (q) over bar’(q) over barq’ channel, and LEP represents
that arising from the knowledge of the collision energy of the
accelerator. The combined value for the W width is
Gamma(W) = 2.404 +/- 0.140(Stat.) +/- 0.077(Syst.) +/- 0.065(FSI)
GeV/c(2).
These results supersede all values previously published by the DELPHI
collaboration.
