Diphoton resonance search with CMS

The results of a search for new physics using high mass diphoton events are exposed. This search employs $3.3 {\rm\ fb}^{-1}$ of pp collision data collected by the CMS experiment in 2015 at a center-of- mass energy of 13 TeV, targeting spin-0 and spin-2 resonances of mass between 500 and 4500 GeV and relative width up to $5.6\times 10^{-2}$. The results of the search are then combined with those obtained by the CMS collaboration in similar searches at $\sqrt{s} = 8$ TeV.
