The decay of $N^{\ast }$(1895) to light hyperon resonances

Abstract

In this talk I review the findings of our recent works where we have studied the decay of $N^{\ast }(1895)$ 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 $N^{\ast }(1895)$ and report the details of our investigation of its decays to different meson-baryon systems and to final states involving $\Lambda (1405)$ and a proposed $\Sigma (1400)$. We find that the width of $N^{\ast }(1895)$ gets important contributions from the decay to light hyperon resonances. Such an information can be used to look for alternative processes to study $N^{\ast }(1895)$ in experimental data.
