Results from a Dynamical Model of Pion Photo- and Electro-production on the Nucleon
Abstract
We present calculations based on a relativistic dynamical model for pion photo- and electro-production from the nucleon. We examine our predictions for the most significant multipoles for photoproduction as compared to those extracted from the available data. We pay particular attention to the ratio of electric to magnetic multipoles that involve the Δ (1232). We also compare our calculations to the available data for electroproduction and examine the dependence of the multipoles on Q^2. Using the generality of our model we can investigate the Q^2 dependence of the electromagnetic form factors of the Δ resonance.
