Sažetak
The increasing body of experimental data motivates us to investigate a new contribution to the radiative KL → π +π −γ decay, which is O(p 4 ) within the framework of the chiral perturbation theory. The new contribution refers to the ∆S = 1 WZW action term, established recently for the direct, O(p 4 ), KL → γγ(−) decay amplitude. We present additional evidence in support of such flavour-changing generalization of the WZW action term as a viable parametrisation of the anomalous radiative non-leptonic kaon decays.
