Search for narrow high-mass resonances in proton-proton collisions at √s = 8 TeV decaying to a Z and a Higgs boson. Physics Letters, Section B, 748, 255-277. doi:10.1016/j.physletb.2015.07.0110370-2693https://doi.org/10.1016/j.physletb.2015.07.011https://hdl.handle.net/11147/5861A search for a narrow, high-mass resonance decaying into Z and Higgs (H) bosons is presented. The final state studied consists of a merged jet pair and a τ pair resulting from the decays of Z and H bosons, respectively. The analysis is based on a data sample of proton–proton collisions at a center-of-mass energy of 8 TeV, collected with the CMS experiment in 2012, and corresponding to an integrated luminosity of 19.7 fb−1. In the resonance mass range of interest, which extends from 0.8 to 2.5 TeV, the Z and H bosons are produced with large momenta, which implies that the final products of the two quarks or the two τ leptons must be detected within a small angular interval. From a combination of all possible decay modes of the τ leptons, production cross sections in a range between 0.9 and 27.8 fb are excluded at 95% confidence level, depending on the resonance mass. © 2015 CERN for the benefit of the CMS Collaborationeninfo:eu-repo/semantics/openAccessBoosted TopologyCmsJetsPhysicsResonance ProductionTau LeptonsArticle2-s2.0-8504176532810.1016/j.physletb.2015.07.01110.1016/j.physletb.2015.07.011
