\begin{document}$ N^*(890) $\end{document} \begin{document}$ 1/2^- $\end{document} baryon is studied in a flavor \begin{document}$ S U(3) $\end{document} scheme with K-matrix unitarization, by fitting to low-energy cross section and phase shift data. It is found that \begin{document}$ N^*(890) $\end{document} co-exists with low-lying poles in other channels, which have been extensively discussed in the literature, though they belong to different octets in the \begin{document}$ S U(3) $\end{document} limit. Hence, the existence of \begin{document}$ N^*(890) $\end{document} is further verified."> On lowest-lying 1/2<sup>−</sup> octet baryons -
