On four-quark interaction, induced by instantons

Four-fermion interaction of u, d-quarks, conditioned by the presence of instantons is investigated. A possibility of scalar and pseudoscalar condensate precipitation, leading to a spontaneous violation of CP-parity is demonstrated. Ratios, relating the current quark masses with their dynamic masses and parameters, defining the degree of CP-violation are found from the self-consistent conditions. The mass matrix of scalar and pseudoscalar mesons, which are bound states of quarks, is calculated
