Title: Searches for a heavy scalar boson $$ \mathrm{H} $$ decaying to a pair of 125 GeV Higgs bosons $$ \mathrm{ hh } $$ or for a heavy pseudoscalar boson $$ \mathrm{A} $$ decaying to $$ \mathrm{Zh} $$, in the final states with $$\mathrm{h} \to \tau \tau$$

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-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.
