By means of forward sum-rules for γγ and gg scattering we show that a spin-0 resonance with mass of the order of the TeV and a sizable γγ or gg partial width -of the order of a few GeV- must be accompanied by higher spin resonances with JR≥2 with similar properties, as expected in strongly coupled extensions of the Standard Model or, alternatively, in higher dimensional deconstructed duals. Furthermore, independently of whether the 750 GeV diphoton candidate is a scalar or a tensor, the large contribution to the forward sum-rules in the referred scenario implies the presence of states in the spectrum with JR≥2, being these high spin particles a manifestation of new extra-dimensions or composite states of a new strong sector.
