Gauge boson couplings at LEP
Self couplings among electroweak gauge bosons are a consequence of the non-Abelian structure of the Standard Model (SM) of electroweak interactions [1]. The measurement of triple (TGC) and quartic couplings (QGC) has been one of the main activities of the LEP experiments (ALEPH, DELPHI, L3 and OPAL) after the ee centreof-mass energy ( √ s) was raised above the threshold for the production of tw...
متن کاملHiggs Boson Searches at Lep
The results of the Higgs boson searches performed by the four LEP experiments at centre-of-mass energies between 189 GeV and 209 GeV corresponding to an integrated luminosity of 2461 pb −1 are presented here. Searches have been performed for Higgs in the Standard Model (SM), in 2 Higgs Doublet Models (2HDM's), for doubly charged, fermiophobic and invisible Higgs as well as a decay mode independ...
متن کاملMSSM Predictions of the Neutral Higgs Boson Masses and LEP II production cross sections
E-mail: [email protected] E-mail: [email protected] E-mail: DEBOERW@CERNVM E-mail: [email protected] E-mail: [email protected] Within the framework of the Minimal Supersymmetric Standard Model (MSSM) the Higgs masses and LEP II production cross sections are calculated for a wide range of the parameter space. In addition, the parameter space restricted b...
متن کاملW-pair Production at Lep
We review here the measurements of W-pair production and W decay rates performed by the four LEP experiments at √ s from 161 to 209 GeV, and their relevance in support of the standard electroweak model.
متن کاملQuartic Gauge Boson Couplings Results at Lep
The study of charged and neutral boson vertices has been performed in different production channels at the LEP experiments. Decay rates and kinematic properties of these events are exploited to set constraints on the corresponding gauge couplings.
