Abstract
We explore the possibility of explaining the recent $\ensuremath{\sim}750\text{ }\text{ }\mathrm{GeV}$ excesses observed by ATLAS and CMS in the $\ensuremath{\gamma}\ensuremath{\gamma}$ spectrum in the context of a compelling theory of naturalness. The potential spin-zero resonance responsible for the excesses also requires the existence of new heavy charged states. We show that both such features are naturally realized in a see-saw composite Higgs model for electroweak symmetry breaking, where the new pseudo-Goldstone bosons are expected to be comparatively heavier than the Standard Model Higgs, and the new fermions have masses in the TeV range. If confirmed, the existence of this new resonance could be the first stone in the construction of a new theory of naturalness.
