Search for Resonance Contributions in Multi Pion Electroproduction with CLAS at Jefferson Lab

OSTI ID:824432
Electroproduction data from CLAS at Jefferson Lab are being analyzed in order to identify resonant couplings to baryon resonances decaying into {pi}{Delta}, pN, or {omega}N. A multi-dimensional fit to the new two-pion electroproduction data not only provides better determined photocouplings of several resonances, but also implicates a significant correction of the hadronic couplings of resonances at W approx. 1.7 GeV. The electroproduction of w shows strong indications of u- and s-channel contributions at W below 2 GeV.
