摘要：

We study the unknown coupling constants that appear at 0(p4) in the chiral perturbation theory analysis of K --> pigamma* --> pil+l-, K+- --> pi+-gammagamma [1] and K --> pipigamma [2] decays. To that end, we compute the chiral realization of the DELTAS = 1 Hamiltonian in the framework of the 1/N(c)-expansion of the low-energy action proposed in [3]. The phenomenological implications are also discussed.
