摘要: A search for the standard model Higgs boson decaying into two Z bosons with subsequent decay a final state containing quark jets and leptons, H to ZZ(*) q q-bar l-l+ is presented. Results are based on data corresponding an integrated luminosity of 4.6 inverse femtobarns proton-proton collisions at sqrt(s)=7 TeV, collected CMS detector LHC. In order discriminate between signal background events, kinematic topological quantities, including angular spin correlations products, employed. Events further classified according probability originate from quarks light or heavy flavor gluons. No evidence found, upper limits its production cross section determined mass 130 600 GeV.
