Search for a massive resonance decaying into a Higgs boson and a W or Z boson in hadronic final states in proton-proton collisions at √s = 8 TeV

Journal of High Energy Physics 2016.2 (2016): 145 reproduced by permission of Scuola Internazionale Superiore di Studi Avanzati (SISSA)Artículo escrito por muchos autores, sólo se referencian el que aparece en primer lugar, el nombre del grupo de colaboración y los autores que firman como pertenecientes a la UAMA search for a massive resonance decaying into a standard-model-like Higgs boson (H) and a W or Z boson is reported. The analysis is performed on a data sample corresponding to an integrated luminosity of 19.7 fb−, collected in proton-proton collisions
at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC. Signal events, in
which the decay products of Higgs, W, or Z bosons at high Lorentz boost are contained
within single reconstructed jets, are identified using jet substructure techniques, including
the tagging of b hadrons. This is the first search for heavy resonances decaying into HW
or HZ resulting in an all-jet final state, as well as the first application of jet substructure
techniques to identify H → WW∗ → 4q decays at high Lorentz boost. No significant signal
is observed and limits are set at 95% confidence level on the production cross sections of W' and Z' in a model with mass-degenerate charged and neutral spin-1 resonances. Resonance masses are excluded for W' in the interval [1.0, 1.6] TeV, for Z' in the intervals [1.0, 1.1] and [1.3, 1.5] TeV, and for mass-degenerate W' and Z' in the interval [1.0, 1.7] TeVFinally, we acknowledge the enduring support for the construction and
