Single pi{sup 0} electroproduction from CLAS data at Jefferson Lab
New measurements of the electroproduction of the Delta (1232) resonance through the p(e, e'p) pi{sup 0} and p(e, e'p) pi{sup 0} 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 Q{sup 2}=(0.3-1.2 GeV{sup 2}). Decay angular distributions in the p pi{sup 0} center-of-mass were obtained over the full range of cos theta{sub c.m.} and phi {sub c.m.}. The high statistical accuracy of this data set is expected to provide strong constraints on dynamic models of the N --> Delta transition form factors.
