Search for new physics in events with collimated photons and gluons
Abstract: This letter reports the results of a search for physics beyond the standard model. The search is performed with events containing jets with substructure resulting from new particles decaying into a photon and two gluons. Jet substructure techniques are adapted to develop a new approach for photon identification in a dense hadronic environment. The proton-proton collision data analyzed were collected by the CMS experiment at $\sqrt{s}= $ 13 TeV during 2016 and correspond to an integrated luminosity of 35.9 fb$^{-1}$. No statistically significant excess is observed and the first cross section limits on processes yielding such events are set.
