Description

The 750 GeV diphoton resonance could be a heavy pion of a new strong dynamics sector with a confinement scale $\mathcal{O}(1\text{ TeV})$. New fermions, vector-like under the strong dynamics group, are chiral under a new $U(1{)}^{\prime }$ gauge symmetry such that their masses are related to the $U(1{)}^{\prime }$-breaking scale or the confinement scale. Our model predicts a phenomenologically rich spectrum near the TeV scale, including a testable decay channel of the 750 GeV resonance into a photon plus $Z^{\prime }$ boson, which naturally has a large leptonic branching ratio.
