New signatures for top in hadron collider

We study the signatures for new TeV resonances that couple to top or bottom quarks both at the Tevatron Run II and at the LHC. We find that it is possible to study these resonances when they axe produced in association with a pair of heavy quarks or in association with a single top at the LHC. In particular, with an integrated luminosity of 300 fb(-1) at the LHC, it is possible to probe resonance masses up to around 2 TeV.
