\title{\boldmath{ $\Xi^-(1950)$}\ \ \ \ \ \ \ $***$}
\maketitle
The $\Xi^-(1950)$ is a member of the isospin doublet containing two strange quarks from the third nucleon like $SU(5)$ multiplet. The mass and width are taken from \cite{Yao:2006px}. The branching ratios are uncertain and we assume an equal branching ratio in two the two observed states. This state is only included to complete the multiplet although it is not assigned this r\^{o}le in \cite{Yao:2006px}. The lower limit on the mass is set so that the dominant mode is accessible and the upper limit is set to ten times the width.
The $\Xi^-(1950)$ has mass $1959$~MeV and is unstable. The $\Xi^-(1950)$ has spin $1/2$, charge $-1$ and is colour neutral.
 The $\Xi^-(1950)$ is a baryon$40$plet.The $\Xi^-(1950)$ has width $60$~MeV. The lower limit on the mass of the particle is $330$~MeV and the upper limit is $600$~MeV. These are the deviations from the on-shell value. The branching ratios are fixed.
The properties of the particle and its antiparticle are taken to be charge-conjugate to each other.
 The PDG code is 23312.
