Using MadGraph5_aMC @ NLO, parton processes were taken into account in five (three) orders of perturbation theory in quantum chromodynamics in the tree approximation (with the inclusion of virtual particle emission in intermediate states). The results of the calculations are consistent with the data for cross sections in the production of c-anti-c and b-anti b quarks. The baryon cross sections differ from the results of ALICE, CMS, and LHCb. Total differential cross section for the Higgs-strathlung process is obtained. This process with electrons, positrons, and the Higgs boson is planned to be measured at the ILC to determine restrictions on the coupling constants of the Higgs boson with two Z-bosons. The observables are selected, measurements of which give the most stringent constraints on these constants. The dependencies of these observables on the coupling constants are analyzed.
