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