We consider the implications of an extended color group SU(3${)}_{\mathrm{I}}$×SU(3${)}_{\mathrm{II}}$ spontaneously broken to SU(3${)}_{\mathit{c}}$ at a TeV or lower scale for the hadronic colliders. The associated massive color octet gauge bosons (the colorons) can enhance the tt¯ pair production at the Fermilab Tevatron collider. At the CERN LHC, the colorons can be pair produced, each decaying to a tt¯ 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 LHC energies, and compare these with the expectations from the standard model.
