Khachatryan, V.Işıldak, Bora2016-07-292016-07-292016-08-100370-2693http://hdl.handle.net/10679/4320https://doi.org/10.1016/j.physletb.2016.05.087A search is performed for a new resonance decaying into a lighter resonance and a Z boson. Two channels are studied, targeting the decay of the lighter resonance into either a pair of oppositely charged τ leptons or a View the MathML source pair. The Z boson is identified via its decays to electrons or muons. The search exploits data collected by the CMS experiment at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.8 fb−1. No significant deviations are observed from the standard model expectation and limits are set on production cross sections and parameters of two-Higgs-doublet models.engrestrictedAccessarticle75936939400038040920005110.1016/j.physletb.2016.05.087CMSPhysicsHiggs2HDMBSMb-TaggingTauLepton2-s2.0-84973595082
