Description

We investigate $K\Lambda$ strong-interaction dynamics around the $N(1535)$ resonance produced in $\Lambda^+_c$ decays in the framework of chiral unitary approach. Coupled-channel effects of $\pi N$, $K \Lambda$, $K \Sigma$, and $\eta N$ are incorporated, and the $N(1535)$ resonance is dynamically generated within this formalism. With natural model parameters, we determine the properties of $N(1535)$. More accurate experimental data on $\Lambda^+_c$ decays will help us better understand the poorly known nature of low-lying exotic states.
