| Publication Abstract: | An analysis of pion electroproduction data, off proton targets, with energies 1.13 GeV < W < 1.6 GeV and Q2 below 4 GeV2, is performed using a general parametrization of transition amplitudes and constraints from gauge invariance and threshold behavior. The model is an extension of the latest Julich-Bonn solution incorporating constraints from pion-induced and photoproduction data. Performing large scale fits (? 105 data) we find a set of solutions with ?2_dof = 1.69 - 1.81 which allows us to assess the systematic uncertainty of the approach. | ||
