Search for the Standard Model Higgs boson in e + e − collisions at √ s ≈ 192 – 209 GeV OPAL
نویسندگان
چکیده
A search for the Standard Model Higgs boson has been performed with the OPAL detector at LEP based on the full data sample collected at √ s ≈ 192–209 GeV in 1999 and 2000, corresponding to an integrated luminosity of approximately 426 pb−1. The data are examined for their consistency with the background-only hypothesis and various Higgs boson mass hypotheses. A lower bound of 109.7 GeV is obtained on the Higgs boson mass at the 95% confidence level. At higher masses, the data are consistent with both the background and the signal-plus-background hypotheses. 2001 Elsevier Science B.V. All rights reserved.

Search for the Standard Model Higgs Boson in OPAL
A search for the Standard Model Higgs boson with the OPAL detector at LEP was reported. The analysis was based on the full data sample collected at √ s ≈ 192–209 GeV in 1999 and 2000, corresponding to an integrated luminosity of approximately 426 pb −1. The data shows an excess in a range of 95–120 GeV. The data slightly favour the hypothesis that a signal is present, but also that the data are...
متن کاملComments on the possible discovery of the Higgs boson with mass ∼ 160 GeV at the Tevatron
The consequences of the possible discovery of the Higgs boson with a mass around 160 180 GeV at the Tevatron are discussed. Most probably, the search for the Higgs boson will be finalized within few years. Its discovery will close the large hole in the foundation of the Standard Model (SM) of elementary particles. At the end of 2000, just before the LEP collider was shut down, the four experime...
متن کاملSearch for Sm and Mssm Higgs Bosons at Lep *
The four LEP experiments (ALEPH, DELPHI, L3 and OPAL) collected around 2.5 fb data in total at energies √ s ≥ 189 GeV of which 536 pb was registered at √ s = 206−209 GeV in 2000. The data are used to search for Higgs bosons in a variety of models. In the Standard Model (SM) the electroweak (EW) symmetry is broken via the Higgs mechanism generating the masses of elementary particles. This implie...
متن کاملSearch for Neutral Higgs Bosons in e+e− Collisions
This thesis is devoted to the search for neutral Higgs bosons predicted by various theoretical models. The Higgs boson arises as a result of spontaneous breaking of SU(2) symmetry leading to the generation of masses of fermions and weak bosons. The search is done in all experimentally related channels using the data collected at center-of-mass energies √ s up to 209 GeV in the years 1998-2000 w...

The latest preliminary combined results of the Higgs boson searches from the LEP experiments ALEPH, DELPHI, L3 and OPAL are presented. A general scan of the MSSM parameters is performed and leads to stringent lower mass limits and for the first time excludes low tanβ values. Presented at the Seventh International Symposium on Particles, Strings, and Cosmology, PASCOS–99, Granlibakken, USA, Dec....
