Description

The decay η → π+π-γ is analyzed using two recently developed chiral models which incorporate vector mesons. One of the models generates a rate and photon spectrum which give an excellent fit to the experimental data. That model is then used to calculate KL → π+π-γ, and a rate which matches the experimental one is obtained with reasonable values of SU(3) breaking parameters. (author) 10 refs., 5 figs
