Abstract:
We report on a search for resonant production of high mass photon pairs. The search employs 12.9fb112.9\,\mathrm{fb^{-1}} of pp collision data collected by the CMS experiment in 2016 at a centre-of-mass energy of 13TeV13\,\mathrm{TeV}. It is aimed at spin-0 and spin-2 resonances of mass between 0.50.5 and 4.5TeV4.5\,\mathrm{TeV} and width, relative to the mass, up to 5.6×1025.6\times10^{-2}. The results of the search are combined statistically with those previously obtained by the CMS collaboration at s=8\sqrt{s}=8 and 13TeV13\,\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.
