Abstract
A search for a heavy scalar boson H decaying into a pair of lighter standard-model-like 125GeV Higgs bosonshhand a search for a heavy pseudoscalar bosonA decaying into a Z and an h boson are presented. The searches are performed on a data setcorresponding to an integrated luminosity of 19.7fb−1of ppcollision data at a centre-of-mass energy of 8TeV, collected by CMS in 2012. Afinal state consisting of two τleptons and two b jets is used to search for the H →hhdecay. Afinal state consisting of two τleptons from the hboson decay, and two additional leptons from the Zboson 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<350GeVand 220 <mA<350GeV.
