Abstract

In this talk I review the findings of our recent works where we have studied the decay of N ∗ (1895) and the implications of such properties on the photoproduction of light hyperons. I discuss that meson-baryon interactions play an essential role in describing the nature of N ∗ (1895) and report the details of our investigation of its decays to different meson-baryon systems and to final states involving Λ(1405) and a proposed Σ(1400). We find that the width of N ∗ (1895) gets important contributions from the decay to light hyperon resonances. Such an information can be used to look for alternative processes to study N ∗ (1895) in experimental data.
