Searches for a heavy scalar boson H decaying to a pair of 125 GeV Higgs bosons hh or for a heavy pseudoscalar boson A decaying to Zh, in the final states with h→ττ. Physics Letters, Section B, 755, 217-244. doi:10.1016/j.physletb.2016.01.0560370-2693https://doi.org/10.1016/j.physletb.2016.01.056https://hdl.handle.net/11147/6205A 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−1 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. © 2016 CERN for the benefit of the CMS Collaborationeninfo:eu-repo/semantics/openAccessCmsHiggsMssmPhysicsΤArticle2-s2.0-8504081601310.1016/j.physletb.2016.01.05610.1016/j.physletb.2016.01.056
