Weak production and electroproduction of $\Delta \mathrm{}\left(1236\right)\mathrm{}$ in a Zucker-model calculation

Zucker's model for weak production and electroproduction of $\Delta \mathrm{}\left(1236\right)\mathrm{}$ is reconsidered in the light of recent experimental data. We find that the disagreement between the predictions of the Zucker model and the experimental data can be significantly reduced by choosing a different form for $\omega$ exchange.
