We present the final results of a search in the CMS detector at LHC for high-mass and narrow resonances decaying into a Higgs and a Z SM bosons in the final state with a pair of tau leptons and a pair of quarks. In the resonance mass range of interest 1.0 - 2.5 TeV, the Z and Higgs bosons are produced with large momenta compared with their masses, which implies that the final products of the two quarks or the two taus must be detected within a small angular separation. From a combination of all possible decay modes of the tau lepton, heavy spin-1 resonances production cross sections are excluded at 95 % C.L. in a range between 0.9 and 27.8 fb, depending on the resonance mass. This analysis is in the context of many searches for heavy resonances decaying into dibosons in the CMS experiment, studying 19.7/fb of integrated luminosity of sqrt(s) = 8 TeV proton-proton collisions.
