The (e+e- -> t tbar H) process has been extensively studied to determine the accuracy on the top-Higgs Yukawa coupling achievable with the TESLA collider at 800 GeV, for Higgs masses ranging from 120 GeV/c2 to 200 GeV/c2. The analysis of (H -> b bbar) and (H -> WW) channels has already shown that an accuracy on the top-Higgs Yukawa coupling better than about 10 % was achievable for most of...

Recent developments in the treatment of a system of heavy quarks close to their production threshold are discussed. Particular emphasis is put on the next-to-next-to-next-to-leading order corrections to the energy levels and the wave function and their effect on the cross section sigma(e+e- -> t tbar). Furthermore, the resummation of logarithmic corrections within the framework of potential...
