Searches for a high mass higgs boson at the Tevatron

Abstract

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/c2 to 200 GeV/c2, 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-1. 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/c2 to 200 GeV/c2. The combined Tevatron results exclude SM Higgs boson mass of 160 < mH < 170 GeV/c2.
