Abstract

We suggest a unified description of baryon form factors in terms of a two-component model with an intrinsic q3 structure and a meson [Formula: see text] cloud, parameterized in terms of vector mesons. We use this model to study the N-Δ form factors. The results are in excellent agreement with data. The N-Δ transition appears to be dominated by coupling to the ρ meson.
