A 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 τpair resulting from the decays of Z and Hbosons, respectively. The analysis is based on a data sample of proton–proton collisions at a center-of-mass energy of 8TeV, collected with the CMS experiment in 2012, and corresponding to an integrated luminosity of 19.7fb−1. In the resonance mass range of interest, which extends from 0.8 to 2.5TeV, the Z and H bosons are produced with large momenta, which implies that the final products of the two quarks or the two τleptons must be detected within a small angular interval. From a combination of all possible decay modes of the τleptons, production cross sections in a range between 0.9 and 27.8fb are excluded at 95% confidence level, depending on the resonance mass.

Abstract
A 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 τpair resulting from the decays of Z and Hbosons, respectively. The analysis is based on a data sample of proton–proton collisions at a center-of-mass energy of 8TeV, collected with the CMS experiment in 2012, and corresponding to an integrated luminosity of 19.7fb−1. In the resonance mass range of interest, which extends from 0.8 to 2.5TeV, the Z and H bosons are produced with large momenta, which implies that the final products of the two quarks or the two τleptons must be detected within a small angular interval. From a combination of all possible decay modes of the τleptons, production cross sections in a range between 0.9 and 27.8fb are excluded at 95% confidence level, depending on the resonance mass.File | Dimensione | Formato | |
