Search for resonant production of high mass photon pairs using 12.9 fb−1 of proton-proton collisions at √s = 13 TeV and combined interpretation of searches at 8 and 13 TeV

The CMS Collaboration


We report on a search for resonant production of high mass photon pairs. The search employs 12.9 fb−1 of pp collision data collected by the CMS experiment in 2016 at a centre-of-mass energy of 13 TeV. It is aimed at spin-0 and spin-2 resonances of mass between 0.5 and 4.5 TeV and width, relative to the mass, up to 5.6 × 10−2

The results of the search are combined statistically with those previously obtained by the CMS collaboration at √s = 8 and 13 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.
