• A search for the decays of the Higgs and Z bosons to J/[psi] gamma and [Upsilon](nS) gamma (n=1,2,3) is performed with pp collision data samples corresponding to integrated luminosities of up to 20.3 fb-1 collected at s=8 TeV with the ATLAS detector at the CERN Large Hadron Collider. No significant excess of events is observed above expected backgrounds and 95% C.L. upper limits are placed on the branching fractions. In the J/[psi] gamma final state the limits are 1.5x10-3 and 2.6x10-6 for the Higgs and Z boson decays, respectively, while in the [Upsilon](1S,2S,3S) gamma final states the limits are (1.3,1.9,1.3)x10-3 and (3.4,6.5,5.4)x10-6, respectively.
