\title{\boldmath{ $\Sigma_b^0$}\ \ \ \ \ \ \ $**$}
\maketitle
This particle has not been observed, although the other two $\Sigma_b$ baryons have been, \cite{cdf:2007rw} . It mass is taken to be the average of the masses of the observed states. The mass is such that the only strong decay is to the $\Lambda_b$ and a pion and therefore we assumed that this is the only mode. The width is calculated using the decayer and the same strong coupling as for the decay of the $\Sigma_c$ baryons. The $\Sigma_b^0$ is allowed to be off-shell by five times the width.

The $\Sigma_b^0$ has mass $5811.5$~MeV and is unstable. The $\Sigma_b^0$ has spin $1/2$, charge $0$ and is colour neutral.
 The $\Sigma_b^0$ is a baryon and is from the $(56,0^+_0)$ $40$plet.The $\Sigma_b^0$ has width $8.5$~MeV. The lower limit on the mass of the particle is $42.5$~MeV and the upper limit is $42.5$~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 5212.
