Abstract

An attempt to extend chiral perturbation theory to radiative vector meson decays into two neutral pseudoscalars, V0→P0P0 γ, is presented. The effects of (chiral) loops are found to be important. Unambiguous predictions are given for φ→π0π0γ, π0ηγ, ρ{variant}→π0π0γ and other processes to be measured in proposed low-energy e+e- machines. © 1992.
