Title: Extraction and interpretation of {gamma}N{yields}{delta} form factors within a dynamical model

Abstract

Within the dynamical model of Refs. [Phys. Rev. C 54, 2660 (1996); 63, 055201 (2001)], we perform an analysis of recent data of pion electroproduction reactions at energies near the {delta}(1232) resonance. We discuss possible interpretations of the extracted bare and dressed {gamma}N{yields}{delta} form factors in terms of relativistic constituent quark models and lattice quantum chromodynamics calculations. Possible future developments are discussed.
