The color-octet, isosinglet analog of the $ρ$ meson in this theory is produced copiously in hadron colliders. If the mass of this resonance is less than twice the mass of the lightest pseudo-Goldstone bosons, then an important decay mode could be to the color-octet analog of the $η$ and a gluon. The subsequent decay of this $η$ into $\ttbar$ gives rise to top quark events with a hard gluon.10 pages, 3 Latex figuresHigh Energy Physics - Phenomenologytext
