Partial wave analysis of (γ/π)N → ηN reactions within a coupled channel unitary Lagrangian approach*

Partial wave analysis of (γ/π)N → ηN reactions within a coupled channel unitary Lagrangian approach*

The recent Crystal Ball measurements of the eta-meson photoproduction on the proton are analyzed within an unitary coupled-channel Lagrangian approach. The dip observed in the reaction cross section at 1.68 GeV is explained in terms of the interference between the S11(1535) and S11(1650) states. Add...
