How well determined is the N − Δ electromagnetic transition from factor at high Q2?

We explore the sensitivity of the N - Δ(1232) electromagnetic transition form factor, extracted from the inclusive electroproduction data, to the choice of background. We find that the extraction of the transition form factor depends critically on it and the existing inclusive data are consistent with a transition form factor much larger than previous values, showing no serious discrepancy with the Bloom-Gilman duality.
