While the Standard Model has proven very successful in describing particle interactions, several unanswered questions still remain. Alternative models, such as those with an extended Higgs sector, can be consistent with current observations and answer some of these questions. This talk presents a search for a heavy, CP-odd Higgs boson, A, decaying into a Z boson and a 125 GeV Higgs boson, h, with the ATLAS detector at the LHC. The search uses proton–proton collision data at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of 20.3 fb−1. Decays of CP-even h bosons to ττ pairs with the Z boson decaying to electron or muon pairs are considered. The analysis strategies and final results of the search will be presented, as well as a combined result with several other A->Zh decay modes.
