摘要：

We study the signal and backgrounds for the process t (t) over barh,h-->W+W- at the CERN Large Hadron Collider (LHC) and a 100 TeV Very Large Hadron Collider (VLHC). Signals are studied in two-, three-, and four-lepton final states. We find a statistical uncertainty in the top-quark Yukawa coupling at the LHC of 16%,8%,12% for m(h)=130,160,190 GeV, respectively. The statistical uncertainty at the VLHC is likely to be negligible in comparison with the systematic uncertainty.
