Parameter of K meson mixing and non-Abelian anomaly

In this paper, the amplitude of K meson mixing is calculated. Pseudo-Goldstone fields are considered as phases of γ5 transformation of quark fields. A formalism for description of K and π mesons in this approach is given. The amplitude is expressed in terms of matrix elements (O/gs bar sGμνγνd/K) and (O/bar sγνγ5d/K). It is shown that there is a relation between (O/gs bar sGμνγνd/K) and (O/απ G μν G μν/0), This relation is in good agreement with known values for amplitudes. The result for the parameter of K meson mixing is B = 1 + 3m21 16π2f2K = 1 + 0.16. From general consideration it is shown that the correction to the vacuum factorization hypothesis must be positive
