Resumo

The nature of nucleon resonances is still being debated, while much experimental data are accumulated. In this work, we focus on the negative parity resonance N* (1895) which is located in the scattering region of various meson-baryon coupled channels, and such dynamics can be crucial in understanding its properties. To test the relevance of such hadron dynamics, we investigate the decay properties of N* (1895) in detail. We examine how a two pole nature of N* (1895) is compatible with its observed decay properties. Moreover, we find that the resonance decays into final states involving Lambda(1405) and Sigma(1400), where the latter is not yet observed experimentally. Such decay processes can be useful to study the properties of the aforementioned hyperon resonances. (AU)
