Abstract: We discuss the reaction of associated production of the top quark pair and Higgs boson at the future International Linear Collider. We assume that the Higgs boson is light and hence, due to its very small decay width, it is produced on mass shell while the top quarks are produced off shell and they decay, each into 3 fermions. This causes a necessity of studying reactions with seven particles in the final state. Concentrating on one semileptonic channel of such reaction, we illustrate the off mass shell effects and calculate the off resonance background contributions. The latter are calculated with the use of a program carlomat for automatic computation of multiparticle cross sections.
