Abstract

A complete model for the production mechanism of the double-resonance reaction $π N \to V Δ$ , where $V$ is a $J^{P} = 1^{-}$ vector meson and $Δ$ is a $J^{P} = {\frac{3}{2}}^{+}$ isobar, is presented. The model uses dipole ( $J = 1$ ) coupling at the $N$ -Regge- $Δ$ vertex to predict the quark-model results of classes (a) and (b). The remaining class (c) relations are not implied by this model. Only four independent helicity amplitudes are nonvanishing in the dipole model, so that quantitative fits of data will be highly overconstrained.
