A search for the decays of the Higgs and Z bosons to J/?? and ?(nS)? (n = 1, 2, 3) is performed with pp collision data samples corresponding to integrated luminosities of up to 20.3 fb -1 collected at vs = 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/?? final state the limits are 1.5 × 10 -3 and 2.6 × 10 -6 for the Higgs and Z boson decays, respectively, while in the ?(1S, 2S, 3S) ? final states the limits are (1.3, 1.9,, 1.3) x 10 -3 and (3.4, 6.5, 5.4) x 10 -6 respectively.
