Searches and Prospects for Standard Model Higgs boson at the Tevatron.pdfVIP

Hadron Collider Physics Symposium (HCP2008), Galena, Illinois, USA Searches and Prospects for Standard Model Higgs boson at the Tevatron Gregorio Bernardi LPNHE-Paris, Universities of Paris 6 and 7, France on behalf of the CDF and DØ Collaborations 8 We report on results obtained at the Tevatron by the CDF and DØ collaborations up to June 2008 (2.4 fb−1), on 0 searches for standard model (SM) Higgs bosons having a high mass (135-200 GeV). High mass Higgs bosons decay ⋆ ′ 0 dominantly in WW and the presented searches are performed in the leptonic decay modes of the W s. Both direct 2 production (pp¯ →H) and associated production (pp¯ →WH) are studied and eventually combined with all channels p available at the Tevatron. Prospects for SM Higgs searches with the full projected Tevatron statistics are also given. e S 0 1. INTRODUCTION 3 ] The Tevatron experiments are searching for the standard model (SM) Higgs boson which is expected to be the x e footprint of the spontaneous breaking of the electroweak symmetry. This mechanism provides an explanation for the - masses of the elementary particles, which are massless in the unbroken gauge theory, so experimental confirmation p e is eagerly awaited for. Direct searches at LEP have constrained its mass to be above 114.4 GeV [1] while indirect h searches contrain it to be below 190 GeV, when taking into account the direct bound [2]. We report here on the [ ′ searches at high mass (d
