    • Abstract


      A search for the Standard Model boson decaying to two 𝑍 bosons with a subsequent decay to a final state with two leptons and two quark jets, $H \rightarrow ZZ \rightarrow l^{+}l^{-} q\bar{q}$, is presented. Data corresponding to an ntegrated luminosity of 1.6 fb-1 of LHC proton-proton collisions at the centre-of-mass energy of 7 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. The events are classified according to the probability of the jets to originate from quarks of light or heavy flavour 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 and 600 GeV/c2.
