摘要

The spin-5/2 resonance effects are studied within the coupled-channel effective Lagrangian model for baryon resonance analysis. We extend our previous hadronic calculations to incorporate the D-15, F-15, D-35, F-35 states. While the effect of the spin-5/2 resonances to the etaN, KLambda, and KSigma reactions is small, the contribution to the omegaN is found to be important. The results for the "conventional" and Pascalutsa-like spin-5/2 descriptions are discussed.
