Application of a Regge-Pole Model to the Reactionsπ−p→π0n,π−p→ηn, andπ+n→ωp

Abstract

A Regge-pole model with $L-S$ coupling is considered for the reactions $\mathrm{PN}\to P^{\prime }N$ and $\mathrm{PN}\to \mathrm{VN}$. The model is used to analyze the processes ${\pi }^{-}p\to {\pi }^{0}n$, ${\pi }^{-}p\to \eta n$, and ${\pi }^{+}n\to \omega p$. Good agreement is obtained for the momentum-transfer distribution. The density matrix of the $\omega$ meson agrees qualitatively with the available data.
