Abstract: (EDP Sciences)
The unitary isobar model EtaMAID has been updated with an extended list of nucleon resonances, fitted to recent and new data for differential cross sections and polarization observables. The nonresonant background is described by Regge trajectories of omega,rho and a_1, b_1 mesons and in addition Regge cuts, where vector and axial vector mesons are exchanged together with Pomeron and f_2 mesons.
