Search for a CP-odd Higgs boson decaying to Zh in pp collisions at $\sqrts =$ 8 TeV with the ATLAS detector
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?ττ?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?σ(gg→A)×BR(A→Zh)×BR(h→ffˉ)?are 0.098--0.013 pb for?f=τ?and 0.57--0.014 pb for?f=b?in a range of?mA=?220--1000 GeV. The results are combined and interpreted in the context of two-Higgs doublet models.
