Single pi Electroproduction with CLAS
Measurements of the electroproduction of the Delta(1232) resonance through the p(e,e'p)(pi)^o reaction have been performed.The data were taken with the CEBAF Large Acceptance Spectrometer (CLAS} at Jefferson Lab using incident electron energies of 1.5, 2.4 and 4.0 GeV. Elastic and inelastic cross sections were measured simultaneously with continuous coverage over a large range of four-momentum transfer Q^2=(0.34.0 GeV^2).Decay angular distributions in the p(pi)^o center-of-mass were obtained over the full range of cos(theta)c.m. and zc.m. The high statistical accuracy of this data set is expected to provide strong constraints on dynamic models ofthe N -> (Delta) transition form factors. A preliminary partial wave analysis will be presented.
