Abstract
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 is presented. 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 or bb pairs with the Z boson decaying to electron or muon pairs are considered, as well as h bb decays with the Z boson decaying to neutrinos. No evidence for the production of an A boson in these channels is found and the 95% confidence level upper limits derived for (gg A) BR( A Zh) BR(h f f ) are 0.098-0.013 pb for f = and 0.57-0.014 pb for f = b in a range of m A = 220-1000 GeV. The results are combined and interpreted in the context of two-Higgs-doublet models.
