Search for Higgs and Z Boson Decays to J/ψγ and ϒ(nS)γ with the ATLAS Detector
A search for the decays of the Higgs and Z bosons to J/ψγ and ϒ(nS)γ (n=1,2,3) is performed with pp collision data samples corresponding to integrated luminosities of up to 20.3 fb<sup>-1</sup> collected at √s = 8 TeV with the ATLAS detector at the CERN Large Hadron Collider. No signific...

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