Searches for a High Mass Higgs Boson at the Tevatron

چکیده

Recent results obtained by the CDF and DØ collaborations are presented here. These Tevatron Higgs searches look for a Standard Model (SM) Higgs boson decaying into W-boson pairs, with the W-bosons decaying into electron-neutrino or muon neutrino final states. In the mass range of 135 GeV/c to 200 GeV/c, the SM Higgs decays prominently into W-boson pairs. The presented results are based on an integrated luminosity that ranges from 3.0 to 4.2 fb. No significant excess over expected background is observed and the 95% CL limits are set for a Standard Model (SM) Higgs boson for different mass hypotheses ranging from 100 GeV/c to 200 GeV/c. The combined Tevatron results exclude SM Higgs boson mass of 160 < mH < 170 GeV/c .

Searches and Prospects for the Standard Model Higgs Boson at the Tevatron

The Higgs boson is the only elementary scalar particle expected in the standard model (SM). Its discovery would be a major success for the SM and would provide new experimental insights into the electroweak symmetry breaking mechanism. Direct measurements at LEP have excluded a SM Higgs boson with a mass mH < 114.4 GeV at 95% C.L. but constraints from precision measurements nevertheless favor a...

Searches and Prospects for Standard Model Higgs boson at the Tevatron

We report on results obtained at the Tevatron by the CDF and DØ collaborations up to June 2008 (2.4 fb−1), on searches for standard model (SM) Higgs bosons having a high mass (135-200 GeV). High mass Higgs bosons decay dominantly in WW ⋆ and the presented searches are performed in the leptonic decay modes of the W s. Both direct production (pp̄→ H) and associated production (pp̄→ WH) are studied ...

Higgs Searches at the Tevatron a

The Higgs boson is the last missing particle in the Standard Model (SM). Its mass is not determined by the SM, there are however several experimental constraints which bound the Higgs mass to values which are within the reach of the Tevatron collider. Lower bounds are given from direct searches at LEP2. These results exclude Higgs masses below 114.4 GeV at the 95% Confidence Level (C.L.) 1. An ...

Searches for the Standard Model Higgs Boson at the Tevatron

The CDF and DØ experiments at the Tevatron have searched for the Standard Model Higgs boson in data collected between 2001 and 2004. Upper limits have been placed on the production cross section times branching ratio to b ¯ b pairs or W + W − pairs as a function of the Higgs boson mass. Projections indicate that the Tevatron experiments have a chance of discovering a MH = 115 GeV Higgs with the...

Searches for a High Mass Standard Model Higgs Boson at the Tevatron

Higgs boson searches are commonly considered one of the main objectives of particle physics nowadays. The latest results obtained by the CDF and DØ collaborations are presented here when seatching for Higgs boson decaying into a W-boson pair, currently the most sensitive channel for masses greater than 130 GeV. The presented results are based on an integrated luminosity that ranges from 3.0 to ...
