η n photoproduction and nucleon resonances
Abstract
We present results of a recent work on the reaction mechanism of η n photoproduction off the neutron in the range of s ≈ 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 σ1/2,\,σ3/2 are computed and the numerical results are in good agreement with the A2 experimental data.
