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~\mathrm{TeV}

during 2016 and correspond to an integrated luminosity of

35.9~\mathrm{fb}^{-1}

. No statistically significant excess is observed and the first cross section limits on processes yielding such events are set.

Note:
