Description
Recently, eta photoproduction on the neutron has received intense experimental interest at GRAAL, ELSA and MAMI due to the appearance of a sharp structure at around W=1670 MeV. We show that this peak can be explained conventionally within coupled channels chiral dynamics. Also, predictions for the I^s and I^c and other polarization observables in the related gamma p --> pi0 eta p reaction, measured at MAMI, ELSA, GRAAL and other labs, will be presented. This reaction helps shed light on the meson-octet baryon-decuplet interaction in chiral dynamics.
