| dc.description | A dynamical coupled channel approach is used to study $π$ and $ω$--meson production induced by pions and photons scattering from the proton. Six intermediate channels including $πN$, $ηN$, $πΔ$, $σN$, $ρN$ and $ωN$ are employed to describe unpolarized and polarized data. Bare parameters in an effective hadronic Lagrangian are determined in a fit to data for $πN \to πN$, $γN \to πN$, $π^- p \to ωn$, and $γp \to ωp$ reactions at center-of-mass energies from threshold to $W < 2.0$ GeV. The $T$ matrix determined in these fits is used to calculate the photon beam asymmetry for $ω$-meson production and the $ωN \toωN$ total cross section and $ωN$ scattering lengths. | |
