### Description

It is shown that a charged scalar particle $\chi$ of mass around 375 GeV charged under both

$\mathrm{SU}(3)_{\textsc{c}}$ and a new confining

non-abelian gauge interaction can explain the 750 GeV diphoton excess. After

pair production, these interactions confine the exotic scalar into

non-relativistic bound states whose decays into photons can explain the

discrepancy. Taking the new confining group to be $\mathrm{SU}(2)$, we find

$\chi$ must carry an electric charge of $Q \sim [\frac{1}{2}, 1]$ to fit the data.

Interestingly, we find that pair production of the scalars and the subsequent

formation of the bound state dominates over direct bound state resonance

production. This explanation is quite weakly constrained by current searches

and data from the forthcoming run at the LHC will be able to probe our

scenario more fully. In particular, at an invariant mass of around 750 GeV

dijet, mono-jet, di-Higgs and $\text{jet} + \text{photon}$ searches may be the most promising

discovery channels.
