Dynamically Generated $\mathrm{\Xi }(1690)$

We show that the $\mathrm{\Xi }(1690)$ resonance can be dynamically generated in the $s$-wave $\bar{K}\mathrm{\Sigma }$-$\bar{K}\mathrm{\Lambda }$-$\pi \mathrm{\Xi }$-$\eta \mathrm{\Xi }$ coupled-channels chiral unitary approach. In our model, the $\mathrm{\Xi }(1690)$ resonance appears near the $\bar{K}\mathrm{\Sigma }$ threshold as a $\bar{K}\mathrm{\Sigma }$ molecular state and the experimental data are reproduced well. We discuss properties of the dynamically generated $\mathrm{\Xi }(1690)$.
