Searches for exclusive Higgs and Z boson decays into J/ψγ, ψ(2S)γ, and ϒ(nS)γ at √s = 13 TeV with the ATLAS detector

Searches for the exclusive decays of the Higgs and Z bosons into a J/ψ, ψ(2S), or Υ(nS) (n = 1, 2, 3) meson and a photon are performed with a pp collision data sample corresponding to an integrated luminosity of 36.1 fb−1 collected at √s = 13 TeV with the ATLAS detector at the CERN Large Hadron Coll...
