E2 and C2 amplitudes for electroproduction of $\Delta$

Abstract

We compute the amplitudes for the electromagnetic ${\gamma }_{v}N\to \Delta$ transition in the framework of soliton models with quarks and mesons. The ratios E2/M1 and C2/M1 as functions of the photon four-momentum squared are dominated by the contribution of the pion cloud and are in reasonable agreement with the available experimental data.
