Abstract

The constraints for angular decay distributions of resonances photoproduced in the reactions $\gamma B \to PB^*$, $\gamma B \to VB$, and $\gamma B \to VB^*$ in the ``excited quark'' model and the ``interacting quarks'' model, where quark structure is assumed only for baryons, are derived and compared with the corresponding predictions of the usual additive quark model of photoproduction including vector meson dominance and the additivity assumption. All the results of the ``interacting quarks'' model can be derived from the ``excited quark'' model and all the results of the ``excited quark'' model can be derived from the additive quark model.
