Precision Measurements at Lep and Lep-2
The status of the LEP precision measurements is reviewed, covering the electroweak measurements at the Z0, the studies of fermion pair production, and the totally new subject of W physics at LEP-2. The results presented here include both published and preliminary ones. These precision results are used to check the overall consistency of the Standard Model, and in its framework, constraints on i...
متن کاملA Tribute to Lep
After a comment on the performance of LEP some highlights of the LEP1 and LEP2 physics programmes are reviewed. The talk concentrates on the precision measurements at the Z resonance, two fermion production above the Z, W + W − production, ZZ production, indirect limits on the Higgs mass, LEP contributions to the exploration of the CKM matrix, and on the LEP measurements of αs.
متن کاملLessons Learned from Lep
LEP was commissioned in 1989 and closed down in November 2000. During this time it has operated in many different modes, with many different optics and at many different energies. Some of the lessons learnt that might be of general applicability are elucidated.
متن کاملHadronisation at Lep
An overview of recent results from LEP concerning the hadronisation process is presented. Emphasis is placed on the b-quark. The first presented analysis is the measurement of the b-quark fragmentation function. It includes a new, hadronic-model independent method to extract the x-dependence of the non-perturbative QCD component from the measured fragmentation function. This is followed by the ...
متن کاملW Physics at LEP
A summary of the W-boson properties measured by the four LEP collaborations is presented here. These properties are updated to take into account the most recent results presented at the ICHEP98 Conference. 1 WW cross sections and W branching fractions After the period of running at the Z, the centre-of-mass energy of LEP has been progressively increased from 161 GeV, i.e., just above the W pair...
