Continuum Contributions to Vector-Meson Decays. II. BrokenU3Symmetry

Abstract

We have constructed a model for estimating the continuum contributions to the propagators of the vector mesons p, <a, and <f>. With this model, we compute vector-meson decay rates predicted by a model of octet-broken U$ symmetry based on spectral-function sum rules for the propagators. The model is consistent with experiment, but present experimental accuracy is not sufficient to distinguish clearly between the pole-dominance form of the model and the model with continuum included.
