Title Coupled-channel analysis of pion- and eta-electroproduction with the Julich-Bonn-Washington model
Abstract Pion and eta electroproduction data are jointly analyzed for the first time, up to a center-of-massenergy of 1.6 GeV. The framework is a dynamical coupled-channel model, based on the recent Julich-Bonn-Washington analysis of pion electroproduction data for the same energy range. Comparisons are made to a number of single-channel eta electroproduction fits. By comparing multipoles of comparable fit quality, we find some of these amplitudes are well determined over the near-threshold region, while others will require fits over an extended energy range.
