摘要
We investigate the. photoproduction using the effective Lagrangian approach at the tree level. We include eight nucleon resonances, that is, D-13(1520), S-11(1535), S-11(1650), D-15(1675), F-15(1680), D-13(1700), P-11(1710), P-13(1720) as well as possible background contributions. In addition, we introduce the new nucleon resonance N*(1675) which was announced by the GRAAL, CB-ELSA and Tohoku LNS-GeV-gamma experiments. We investigate a possible role of the resonance with testing its spin and parity for four different cases of J(P) = 1/2(+/-) and 3/2(+/-). We calculate various cross sections including beam asymmetries for neutron and proton targets. We find noticeable isospin asymmetry in transition amplitudes for proton and neutron targets.
