Abstract

The interplay between the chiral anomaly and the non-leptonic weak hamiltonian is studied. The structure of the corresponding effective lagrangian of odd intrinsic parity is established. It is shown that the factorizable contributions (leading in 1/N_c) to that lagrangian can be calculated without free parameters. As a first application, the decay K⁺→π⁺π⁰γ is investigated.
