Abstract:

We report on a search for resonant production of high mass photon pairs. The search employs

12.9\,\mathrm{fb^{-1}}

of pp collision data collected by the CMS experiment in 2016 at a centre-of-mass energy of

13\,\mathrm{TeV}

. It is aimed at spin-0 and spin-2 resonances of mass between

0.5

and

4.5\,\mathrm{TeV}

and width, relative to the mass, up to

5.6\times10^{-2}

. The results of the search are combined statistically with those previously obtained by the CMS collaboration at

\sqrt{s}=8

and

13\,\mathrm{TeV}

. Limits are set on scalar resonances produced through gluon-gluon fusion, and on Randall--Sundrum gravitons. No significant excess is observed over the standard model predictions.
