Abstract (data abstract)
CERN-ATLAS. Search for heavy resonances decaying to a photon and a hadronically decaying Z/W/H boson in pp collisions at sqrt{s} = 13 TeV with the ATLAS detector. Many extensions of the Standard Model predict new resonances decaying to a Z, W, or Higgs boson and a photon. This paper presents a search for such resonances produced in pp collision at sqrt{s}=13 TeV using a dataset with an integrated luminosity of 36.1/fb collected by the ATLAS detector at the Large Hadron Collider. The Z/W/H bosons are identified through their decays to hadrons. The data are found to be consistent with the Standard Model expectation in the entire investigated mass range. Upper limits are set on the production cross section times branching fraction for resonance decays to Z/W+gamma in the mass range from 1.0 to 6.8 TeV, and for the first time into H+gamma in the mass range from 1.0 to 3.0 TeV.
