A New Physics Source of Hard Gluons in Top Quark Production

Abstract

We consider the contribution of new strongly interacting sector, with a characteristic scale of half a TeV, to top quark production at the Tevatron. The color-octet, isosinglet analog of the $\rho$ 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 $\eta$ and a gluon. The subsequent decay of this $\eta$ into $\ttbar$ gives rise to top quark events with a hard gluon.
