OSTI ID:840170
We use local quark-hadron duality to estimate the purely nonperturbative soft contribution to the {gamma}*p {yields} {Delta} form factors. Our results are in agreement with existing experimental data. We predict that the ratio G*{sub E}(Q{sup 2})/G*{sub M}(Q{sup 2}) is small for all accessible Q{sup 2}, in contrast to the perturbative QCD expectations that G*{sub E}(Q{sup 2}) {yields} -G*{sub M}(Q{sup 2}).
