The 4th China LHC Physics Workshop (CLHCP 2018)

This talk will present a search for heavy resonance decaying to Z/W/H + an energetic photon using 36.1 fb$^{-1}$ pp collision data collected by the ATLAS detector. Only the hadronic decays of Z/W/H bosons are considered. This search explores the phase space where the boson decay products are close and form a fat jet. No obvious deviations are found with respect to the Standard Model predictions. The model-independent cross section limits are presented as functions of resonance mass for various signal hypotheses.
