Search for Resonance Contributions in Multi Pion Electroproduction with Clas
Abstract
Electroprodution data from CLAS at Jefferson Lab are being analyzed in order to identify resonant couplings to baryon resonances decaying into πΔ, ρN, or ωN. A multi-dimenional 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 ≈ 1.7 GeV. The electroproduction of ω shows strong indications of u- and s-channel contributions at W below 2 GeV.
