Available in PDF, EPUB and Kindle. Book excerpt: 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 [tau] pair resulting from the decays of Z and H bosons, respectively. This analysis is based on a data sample of proton-proton collisions at a center-ofmass 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 [tau] leptons must be detected within a small angular interval. A combination of all possible decay modes of the [tau] 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.
