Abstract

We have extended a model for the γN→ ππN reaction to virtual photons and selected the diagrams which have a Δ in the final state. The agreement found with the γ_v p→Δ⁰π⁺ and γ_v p→Δ⁺⁺π^- reactions is good. The sensitivity of the results to NΔ transition form factors is also studied. The present reaction, selecting a particular final state, is an extra test for models of the γ_v N→ ππN amplitude.
