Abstract

We show that quarkonia-like states of a hidden SU(N ) gauge group can account for the 750 GeV diphoton excess observed by ATLAS and CMS, even with constituents carrying standard model hypercharge only. The required hypercharge is modest, varying between about 1.3–1.6 for strong SU(N ) coupling, to 2–3 for weak SU(N ) coupling, for N = 3, 4. This scenario predicts a variety of diphoton and multi-photon resonances, as well as photons from continuum pair production, and possibly exotic decays into standard model fermions, with no significant multi-jet resonances.
