Tests of the Standard Model at Lep
Measurements made by the four LEP experiments of electroweak parameters and the strong couphng constant are presented. These are used in an overaU Standard Model fit and a constraint on the mass of the top quark is derived. 1. Precision Measurements of Electroweak Parameters During 1989, 1990 and 1991 the four main experiments at the LEP e+ecollider (ALEPH, DELPHI, L3 and OPAL) have recorded da...
متن کاملPrecision Tests of the Standard Model at Lep and Results from the 4-jet Final State at Lep 1.5
First a short review is made of current limits on the Standard Model as derived from the electroweak sector concerning the Z boson at LEP. The second part of the paper presents an analysis of the four jet nal state at ALEPH, this analysis was performed on LEP data taken at centre of mass energies of 130 and 136 GeV. The results presented here are from approximate totals 1 of 12.3 millionhadroni...
متن کاملPrecision Tests of the Electroweak Interactions at Lep / Slc
This paper is an updated version of the invited plenary talk given at the XXII Physics in Collision Conference at Stanford, (June 2002). The measurements performed at LEP and SLC have substantially improved the precision of the tests of the Minimal Standard Model. The precision is such that there is sensitivity to pure weak radiative corrections. This allows to indirectly determine the top mass...
متن کاملStandard Model Physics at Lep
Abstract. Selected topics on precision tests of the Standard Model of the Electroweak and the Strong Interaction at the LEP e+e− collider are presented, including an update of the world summary of measurements of αs, representing the state of knowledge of summer 1999. This write-up of lecture notes1 consists of a reproduction of slides, pictures and tables, supplemented by a short descriptive t...
متن کاملPrecision Tests of the Standard Model
Recent published and preliminary precision electroweak measurements are reviewed, including new results on the mass of the top quark and mass and width of the W boson. The experimental results are compared with the predictions of the Standard Model and are used to constrain its free parameters, notably the mass of the Higgs boson. The agreement between measurements and expectations from theory ...
