Abstract
New measurements of the electroproduction of the Δ(1232) resonance through the p(e,e′p)π0 and p(e,e′p)π0 reactions have been performed. The data were taken with the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab using polarized and unpolarized incident electron beam. Cross sections were measured simultaneously with continuous coverage over a large range of four-momentum transfer Q2=(0.3−1.2 GeV2). Decay angular distributions in the pπ0 center-of-mass were obtained over the full range of cos θc.m. and φc.m.. The high statistical accuracy of this data set is expected to provide strong constraints on dynamic models of the N→Δ transition form factors.
