SEARCH FOR LIGHT HIGGS BOSON AT LHC VIA PRODUCTION THROUGH WEAK BOSON FUSION K.MAZUMDAR On behalf of CMS Collaboration, CERN Experimental High Energy Physics Group, Tata Institute of Fundamental Research, Mumbai 400 005, 3 0 India EP Division, CERN, Geneva. 0 2 g u A 9 2 1 v 0 7 0 8 The LHC potential for observing a light Higgs boson produced through Weak Boson Fusion 0 3 mode, qq → qqH, is presented. For non-hadronic decays modes of the Higgs boson the process 0 is identified with a final state containing two energetic forward-backward jets, separated with / a large rapidity and a hadronically quiet central region. The use of these properties, combined x with special features of some of the decay modes enhances the potential of an early discovery e- of a light Higgs boson both in the Standard Model and beyond. The recent studies done in p the context of CMS experiment are discussed. e h : v 1 Higgs Boson Discovery at LHC i X r The primary goal of the large hadron collider (LHC), is to unravel the mystery of the electroweak a symmetry breaking. The search for the Standard Model (SM) Higgs boson has therefore been one of the main motivations behind enormous efforts put in by the omni-purpose p-p exper- iments, ATLAS and CMS, in the LHC. The first collisions at the LHC, at a centre-of-mass energy of 14 TeV, are expected by June 2007. By 2010 the accumulated luminosity will be 30 fb−1/experiment, increased to 100 fb
