Abstract

Radiative transitions between vector and pseudoscalar mesons are analyzed in a model utilizing SU(N)-flavor symmetry plus breaking from unequal-quark masses, gluon annihilation channels, and particle mixing. Best fits from the light-quark sector propagate terms into the charm sector which require fine-tuning of parameters to remain consistent with data. We conclude that it is unlikely that such models can survive similar extensions to the t- and b-quark sectors without substantial modification.
