  We study the jet activity that accompanies the production by gluon fusion of
a new physics scalar particle decaying into photons at the LHC. In the
considered scenarios, both the production and decay mechanisms are governed by
loop-induced interactions involving a heavy colored state. We show that the
presence of large new physics contributions to the inclusive diphoton
invariant-mass spectrum always implies a significant production rate of
non-standard diphoton events containing extra hard jets. We investigate the
existence of possible handles that could provide a way to obtain information on
the underlying physics behind the scalar resonance, and this in a wide mass
window.
