Sažetak
The increasing body of experimental data motivates us to investigate a new contribution to the radiative KL --> pi+ pi- gamma decay, which is O(p^4) within the framework of the chiral perturbation theory. The new contribution refers to the Delta S = 1 WZW action term, established recently for the direct, O(p^4), KL --> gamma gamma(-) 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.
