\title{\boldmath{ $\bar{{\Xi'}}_c^-$}\ \ \ \ \ \ \ $****$}
\maketitle
The $\bar{{\Xi'}}_c^-$ is the charged $\Xi_c$ member of the $SU(3)$ sextet which includes the $\Sigma_c$ and $\Omega_c^0$. The mass is taken from \cite{Yao:2006px} but the width has not been measured. Due to the mass difference with the $\Xi_c$ there are no allowed strong decays and therefore we assume that the radiative mode is the only one. We use the theoretical value of the width from \cite{Ivanov:1999bk}  and allow the $\bar{{\Xi'}}_c^-$ to be off-shell by ten times this width.
The $\bar{{\Xi'}}_c^-$ has mass $2575.7$~MeV and is unstable. The $\bar{{\Xi'}}_c^-$ has spin $1/2$, charge $-1$ and is colour neutral.
 The $\bar{{\Xi'}}_c^-$ is a baryon and is from the $(56,0^+_0)$ $40$plet.The $\bar{{\Xi'}}_c^-$ has width $0.0127$~MeV. The lower limit on the mass of the particle is $0.127$~MeV and the upper limit is $0.127$~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 -4322.
