Effective Lagrangian Approach to the Theory of Eta Photoproduction in the $N^{\ast }(1535)$ Region

M. Benmerrouche, N. C. Mukhopadhyay, J. F. Zhang

We investigate eta photoproduction in the $N^{\ast }(1535)$ resonance region within the effective Lagrangian approach (ELA), wherein leading contributions to the amplitude at the tree…
