Precision Electroweak Experiments at Lep
During the operation of the LEP e + e ? collider at the Z resonance from 1989 to 1995 the four experiments ALEPH, DELPHI, L3 and OPAL have collected about 16 million decays of the Z into hadrons and charged leptons. The precise measurements of the total cross section allow an accurate determination of the properties of the Z. Including data up to 1994 one obtains for the mass, the total and par...
متن کاملPrecision Electroweak Physics at Lep
Progress in precisionmeasurements of electroweak observables at LEP continues steadily. The highlights of 1993 are: a new scan of the Z line shape with precise beam energy determination by resonant depolarization, leading to a measurement of the Z width with 1:5 10 3 precision; rst results on absolute cross sections with high-precision luminosity monitors; high e ciency b-tagging with microvert...
متن کاملConstraints on Electroweak Contact Interactions from LEP and Tevatron Data
A complete set of dimension-6 effective contact interactions involving Higgs, gauge bosons and quarks is studied. Limits on the coefficients of these new operators are obtained from the experimental values of the Z and W gauge bosons widths. 12.60.-i,12.60.Fr,12.60.Cn,13.38.-b Typeset using REVTEX 1
متن کاملStandard Model Electroweak Measurements at Lep
Electron-positron collision allow a detailed investigation of the standard model (SM) thanks to their clean experimental conditions. The Large Electron-Positron collider (LEP) was operated at CERN for about 12 years (1989 2000) at increasing center of mass energies ( √ s): both at the Z pole ( √ s ≈ 91 GeV) and beyond ( √ s = 160-209 GeV). Its maximum instantaneous luminosity was 0.5-1 10 cm s ...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
