Search for a heavy Higgs boson A decaying to a Z boson and a SM Higgs boson h with the ATLAS Experiment — •Jike Wang — ATLAS, DESY, Notkestrasse 85, 22607 Hamburg

The first search for a heavy, CP-odd Higgs boson, A, decaying into a Z boson and a 125 GeV Higgs boson, h, using 20.3 fb-1 of proton-proton collision data at a centre-of-mass energy of 8 TeV collected by the ATLAS experiment at the LHC, is presented. Decays of h bosons in tautau or bb pairs with the Z decaying in electron or muon pairs are considered as well as h->bb decays with the Z boson decaying into neutrinos. The results are combined and interpreted in the context of Two-Higgs-Doublet Models.
