Top Quark Signature in Extended Color Theories
  We consider the implications of an extended color group, $SU\left( 3\right) _I\times SU\left( 3\right) _{II}$, spontaneously broken to $SU\left( 3\right) _c$ at a TeV or lower scale, for the hadronic colliders. The associated massive color octet gauge bosons (the colorons) can enhance the $t \overline{t}$ pair production at the Tevatron collider. At the LHC, the colorons can be pair produced, each decaying to a $t\overline{t}$ pair. This gives rise to anomalous multi W production: a clear signature of physics beyond the Standard Model. We calculate the associated multijet and multilepton final states at the Tevatron and the LHC energies, and compare these with the expectations from the Standard Model.
