Fecha de publicación: | 2016 | Editor: | Elsevier | Citación: | Physics Letters B 755: 217-244 (2016) | Resumen: | A search for a heavy scalar boson H decaying into a pair of lighter standard-model-like 125 GeV Higgs bosons hh and a search for a heavy pseudoscalar boson A decaying into a Z and an h boson are presented. The searches are performed on a data set corresponding to an integrated luminosity of 19.7 fb of pp collision data at a centre-of-mass energy of 8 TeV, collected by CMS in 2012. A final state consisting of two τ leptons and two b jets is used to search for the H→hh decay. A final state consisting of two τ leptons from the h boson decay, and two additional leptons from the Z boson decay, is used to search for the decay A→Zh. The results are interpreted in the context of two-Higgs-doublet models. No excess is found above the standard model expectation and upper limits are set on the heavy boson production cross sections in the mass ranges 260<mH<350 GeV and 220<mA<350 GeV. | Descripción: | Open Access funded by SCOAP³ - Sponsoring Consortium for Open Access Publishing in Particle Physics.-- et al. | Versión del editor: | http://dx.doi.org/10.1016/j.physletb.2016.01.056 | URI: | http://hdl.handle.net/10261/140821 | DOI: | 10.1016/j.physletb.2016.01.056 | Identificadores: | doi: 10.1016/j.physletb.2016.01.056 issn: 0370-2693 e-issn: 1873-2445 |
