Search for a Higgs boson in the $H \to ZZ \to l^{+}l^{-}q\overline{q}$ channel with the CMS experiment at the LHC

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->ZZ->llqq is presented. Data corresponding to an integrated luminosity of about 5.1 fb^-1 of LHC proton-proton collisions at sqrt(s...

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->ZZ->llqq is presented. Data corresponding to an integrated luminosity of about 5.1 fb^-1 of LHC proton-proton collisions at sqrt(s)=8 TeV were collected and analysed 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.\n The events are classified according to probability of the jets to originate from quarks of light or heavy flavour. 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 200 and 600 GeV.
