We discuss the reaction of associated production of a top quark pair and aHiggs boson at the future e+e- linear collider that can be used to determinethe top-Higgs Yukawa coupling. Taking into account decays of the top quarks andthe light Higgs boson leads to reactions with 8 fermions in the final statewhich, in the framework of the standard model, receive contributions typicallyfrom many thousands Feynman diagrams. An overwhelming majority of the diagramscomprises the off resonance background to the resonant signal of associatedproduction and decay of the top quark pair and Higgs boson. We address thesignal and background issue by comparing cross sections calculated with thesignal diagrams only and with the complete sets of the diagrams.
