Resonance Decays Involving Vector Mesons

Abstract

A picture of resonance decays using only very general features of the quark model is applied to the case of ${\mathrm{½}}^{+}$ $1^{-}$ final states. Recent experiments on $\pi N\to N\rho$ provide a crucial test of the model, which predicts correctly the dominant spin of the $N\rho$ system in several cases.
