\title{\boldmath{ $B^{*+}_{c0}$}\ \ \ \ \ \ \ $*$}
\maketitle
The $B^{*+}_{c0}$ is the lightest scalar meson containing a bottom and a charm quark. The $B^{*+}_{c0}$ has not been observed and is included to complete the lightest scalar multiplet. The mass is taken from the lattice result in \cite{Brambilla:2004wf}  which agrees with potential model calculations. In common with other calculations the mass difference with the ground state is sufficiently large for the $B^{*+}_{c0}$ to decay to the lighter $B_c$ states and either a photon or pion pair but not the strong decay to a $D$ and $B$ meson. 

  Although the mass difference is sufficient for the the decay to the lightest $B_c$ state and two pions to be kinematically possible this decay is not expected, see \cite{Godfrey:2004ya} , and therefore we assumed the radiative modes to the lightest pseudoscalar are the only ones. The width and branching ratios are taken from \cite{Godfrey:2004ya}  and the $B^{*+}_{c0}$ is allowed to be off-shell by ten times the width.
The $B^{*+}_{c0}$ has mass $6727$~MeV and is unstable. The $B^{*+}_{c0}$ has spin $0$, charge $1$ and is colour neutral.
 The $B^{*+}_{c0}$ is a meson and is from the $1^3P_0$ multiplet.The $B^{*+}_{c0}$ has width $0.055$~MeV. The lower limit on the mass of the particle is $0.55$~MeV and the upper limit is $0.55$~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 10541.
