We consider the possibility of studying novel particles at the TeV scale withenhanced couplings to the top quark via top quark pair production at the LHCand VLHC. In particular we discuss the case of neutral scalar and vectorresonances associated with a strongly interacting electroweak symmetry breakingsector. We constrain the couplings of these resonances by imposing appropriatepartial wave unitarity conditions and known low energy constraints. We evaluatethe new physics signals via WW -> tt~ for various models without makingapproximation for the initial state W bosons, and optimize the acceptance cutsfor the signal observation. We conclude that QCD backgrounds overwhelm thesignals in both the LHC and a 200 TeV VLHC, making it impossible to study thistype of physics in the tt~ channel at those machines.Comment: 15p, add. comments to clarify model, +2 ref., version to appear PR
