Search for Standard Model Higgs Boson in the decay channel $H\rightarrow ZZ\rightarrow l^{+}l^{-} q\overline{q}$ at CMS

A search for the standard model Higgs boson decaying to two Z bosons with subsequent decay to a final state with two leptons and two quark-jets, $H\rightarrow ZZ\rightarrow l^{+}l^{-} q\overline{q}$, is presented. Data corresponding to an integrated luminosity of 1.6 $fb^{-1}$ of LHC proton-proton c...

description A search for the standard model Higgs boson decaying to two Z bosons with subsequent decay to a final state with two leptons and two quark-jets, $H\rightarrow ZZ\rightarrow l^{+}l^{-} q\overline{q}$, is presented. Data corresponding to an integrated luminosity of 1.6 $fb^{-1}$ of LHC proton-proton collisions at the center-of-mass energy of 7 TeV were collected and analyzed by the CMS experiment. The selection to discriminate between signal and background events is based on kinematic and topological quantities, which include the angular spin correlations of the decay products. The events are classified according to probability of the jets to originate from quarks of light or heavy flavor or from gluons. No evidence for a Higgs boson is found and upper limits on the Higgs boson production cross section are set in the range of masses between $226 GeV/c^{2}$ and $600 GeV/c^{2}$.
