Description

The use of the effective Lagrangian with broken chiral UL(3)xUR(3) symmetry makes it possible to estimate a part of amplitude of the transition KS → 2π generated by O5.6 operators of monopole quark-quark ΔI=1/2 interaction. The contribution of these operators depends strongly on the magnitude of the ratio fK/fπ, as well as on the mixing of quark-antiquark scalar mesons with gluonium. This contribution can achieve a magnitude sufficient for quantitative description of the decay. The arising picture of CP violation does not contradict the available data
