ثبت نشده
چکیده
The mass of the W boson is measured at LEP by fully reconstructing the W boson decays. The measurement techniques and systematic uncertainties are presented. The current measurement of the mass of the W boson at LEP yields 80.412 ± 0.042 GeV.

Mass Measurement of the W - boson using the ALEPH Detector at LEP
The W-boson mass has been measured using the ALEPH detector at LEP. Preliminary results from data taken in 1998 are added to previous measurements to give m W = 80.411 ± 0.064(stat.) ± 0.037(syst.) ± 0.022(BE-CR) ± 0.018(LEP) GeV/c 2 .
متن کاملPrecision Higgs boson mass determination at lepton colliders
We demonstrate that a measurement of the Bjorken process e + e − , µ + µ − → ZH in the threshold region can yield a precise determination of the Higgs boson mass. With an integrated luminosity of 100 fb −1 , it is possible to measure the Higgs mass to within 60 MeV (100 MeV) for m H = 100 GeV (150 GeV). One of the triumphs of the LEP program was the measurement of the Z-boson mass to two MeV. E...
متن کاملSpect Q s Flux Loop Global Fit
The W-mass measurements from LEP and the results of a global fit of the Standard Model parameters to the electroweak data are presented. Comprehensive studies of experimental systematic effects allowed a measurement of the W mass with an accuracy of better than half a permill. Especially the recent improvements in the LEP energy calibration, the modelling of the hadronisation process and the un...
متن کاملCalibration of centre - of - mass energies at LEP 2 for a precise measurement of the W boson mass The LEP Energy Working Group
The determination of the centre-of-mass energies for all LEP 2 running is presented. Accurate knowledge of these energies is of primary importance to set the absolute energy scale for the measurement of the W boson mass. The beam energy between 80 and 104 GeV is derived from continuous measurements of the magnetic bending field by 16 NMR probes situated in a number of the LEP dipoles. The relat...
