Jet reconstruction in LHCb searching for Higgs-like particles

One of the greatest challenges in High Energy Physics is the discovery of the Higgs boson which is responsible for the Standard Model particles mass generation. Below ∼150 GeV/c2 the Higgs decay into two b-quarks, H → b b-bar dominates. The two quarks form a string which fragments, giving rise to hadronization in jets containing b-hadrons. The study is focused on the channel where the Higgs boson is produced in association with a gauge boson decaying leptonically H + W → b b-bar + lv and H + Z → b b-bar + ll and Higgs masses are in the range 115 - 140 GeV/c2. The gauge bosons decay produces hard leptons quite often isolated from the b-jets. Hence an isolated lepton with high transverse momentum is required in order to reject the large QCD background. The aim of this work is to explore the feasibility to observe Higgs-like particles at the LHCb experiment at CERN by exploiting the detector capabilities to identify b-jets.
