Recent measurements of the transition form factors for the P* vertices, with P=0, and are compared with different models. These include vector-meson dominance, constituent-quark loops, the QCD-inspired interpolation by Brodsky-Lepage, and chiral perturbation theory. General agreement is observed and differencesdue to SU(3) breaking are stressed and discussed. © 1992 The American Physical Society.
