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 s= 13 TeV during 2016 and correspond to an integrated luminosity of 35.9 fb1. No statistically significant excess is observed and the first cross section limits on processes yielding such events are set.
