Combination of searches for heavy resonances decaying into bosonic and leptonic final states

Combination of searches for heavy resonances decaying into bosonic and leptonic final states: A generic prediction of many extensions of the Standard Model (SM) is the existence of heavy bosons decaying into pairs SM gauge bosons, as well as WH, ZH, or a pair of fermions. Specific searches for diboson resonances in several decay channels were combined to set constraints, using simple benchmark models, on the existence of a heavy hypothetical scalar, vector, or tensor particle. Analyses of leptonic final states  and were further combined with the diboson searches. Limit contours were obtained on the couplings of a heavy vector triplet (HVT) to quarks, leptons and the Higgs boson. The data exclude an HVT boson with mass below 5.5 (4.5) TeV in a weakly-coupled (strongly-coupled) scenario. Limits are also set on a Kaluza-Klein graviton.
