\title{\boldmath{ $h_b$}\ \ \ \ \ \ \ $*$}
\maketitle
The $h_b$ is the lightest pseudovector $b\bar{b}$ state. This particle has not been observed. The mass is taken from \cite{Eichten:1994gt}  which is in broad agreement with most potential models. The width and branching ratios are taken from \cite{Godfrey:2002rp} . The $h_b$ is allowed to be off-shell by ten times the width.
The $h_b$ has mass $9873$~MeV and is unstable. The $h_b$ has spin $1$, charge $0$ and is colour neutral.
 The $h_b$ is a meson and is from the $1^1P_1$ multiplet.The $h_b$ has width $0.0894$~MeV. The lower limit on the mass of the particle is $0.894$~MeV and the upper limit is $0.894$~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 10553.
