Searches at LEP
Searches have been conducted for a broad range of new phenomena by the four experiments ALEPH, DELPHI, L3, and OPAL, at LEP2. Each experiment contributes approximately 150 pb of ee annihilation data with a mean √ s of 205.9 GeV in 2000 to these searches (data prepared for the September 5 LEPC meeting). The statistical procedure for setting limits and evaluating the significance of excesses obse...
متن کاملSusy Searches at Lep
Searches for SUSY particles have been performed in 3.6 fb −1 e + e − data collected by the LEP detectors at √ s between 90 GeV and 209 GeV. This talk reviews some of the relevant searches for SUSY particles at LEP. No excess of events is observed in any channel. Results are interpreted in the context of the MSSM.
متن کاملHiggs Searches at Lep
The four LEP experiments ALEPH, DELPHI, L3 and OPAL have performed decay-mode independent searches for scalar bosons, flavour-independent Higgs boson searches, searches for Higgs bosons in the Standard Model and several Two-Higgs-Doublet models and searches for doubly charged Higgs bosons at centre-of-mass energies up to 209 GeV. The results obtained and mostly combined by the LEP Higgs working...
متن کاملExotic Searches at Lep
In the last five years, the operation of the LEP accelerator has provided the HEP community with a unique opportunity to search for physics beyond the standard model at the typical energy scale of 200 GeV. Although most of the data analysis has been focused on the traditional sectors of Higgs and gravity-mediated SUSY physics, a considerable effort has been dedicated by ALEPH, DELPHI L3 and OPA...
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...
