ηn Photoproduction and Nucleon Resonances

초록

We present results of a recent work on the reaction mechanism of tin photoproduction off the neutron in the range of root s approximate to 1.5 - 1.9 GeV and discuss the role of various nucleon resonances listed in the Particle Data Group (PDG). We make use of an effective Lagrangian approach combining with a Regge method. The total and helicity-dependent cross sections sigma(1/2), sigma(3/2) are computed and the numerical results are in good agreement with the A2 experimental data.
