Abstract: (Springer)

We propose a new explanation for excess events observed in the search for a high-mass resonance decaying into dibosons by the ATLAS experiment. The resonance is identified as a composite spin-0 particle that couples to the Standard Model gauge bosons via dimension-5 operators. The excess events can be explained if the dimension-5 operators are suppressed by a mass scale of

\mathcal{O}\left(1-10\right)

TeV. We also construct a model of hidden strong gauge dynamics which realizes the spin-0 particle as its lightest composite state, with appropriate couplings to Standard Model gauge bosons.
