Abstract

We predict differential decay distributions for phi->rho gamma gamma and phi -> omega gamma gamma using chiral perturbation theory. We also consider the isospin violating decay phi -> omega pi⁰. Experimental information on these decays can be used to determine couplings in the heavy vector meson chiral Lagrangian.
