Comparisons of Model Predictions of Pion Electrioproduction Amplitudes in the low $Q^2$ Region

Abstract

Pion electroproduction amplitudes predicted by three theoretical models in the $Q^2 \leq 0.5$ (GeV/c)$^2$ region are compared. The objective is to facilitate the analyses of the data from new experiments on investigating the pion cloud effects on the $γN \to Δ$ transition form factors.
