Dynamical Models of the Excitations of Nucleon Resonances

Abstract

The development of a dynamical model for investigating the nucleon resonances using the reactions of meson production from πN, γN, N(e,e'), and N(ν,{\it l}) reactions is reviewed. The results for the Δ(1232) state are summarized and discussed. The progress in investigating higher mass nucleon resonances is reported.
