Abstract
A search for heavy, narrow resonances decaying to a Higgs boson and a photon () has been performed in proton-proton collision data at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of collected with the CMS detector at the LHC in 2016. Events containing a photon and a Lorentz-boosted hadronically decaying Higgs boson reconstructed as a single, large-radius jet are considered, and the invariant mass spectrum is analyzed for the presence of narrow resonances. To increase the sensitivity of the search, events are categorized depending on whether or not the large-radius jet can be identified as a result of the merging of two jets originating from quarks. Results in both categories are found to agree with the predictions of the standard model. Upper limits on the production rate of resonances are set as a function of their mass in the range of 720–3250 GeV, representing the most stringent constraints to date.
