The η -baryon octet

Open publisher page 2 citations
Abstract
The recent tantalizing experimental support for an $\ensuremath{\eta}$-baryon ${J}^{P}={\frac{1}{2}}^{\ensuremath{-}}$ unmixed octet challenges conventional model wisdom. The establishment of the $\ensuremath{\Xi}(1868)$ member of the $\ensuremath{\eta}$ octet will give strong affirmation that the negative-parity baryon mass spectrum could be mixing-free.
