\title{\boldmath{ $a_0^+(1450)$}\ \ \ \ \ \ \ $***$}
\maketitle
The $a_0^+(1450)$ is assigned as the charged member of the isospin triplet from the lightest scalar multiplet, due to the uncertainty over which scalar mesons belong to which multiplet this meson could be replaced by the $a_0(980)$. The mass and width are taken from \cite{Yao:2006px}. The branching ratios are not given in \cite{Yao:2006px} and therefore we have used the values for the ratios of branching ratios
\begin{eqnarray}
\frac{\Gamma(\pi\eta')}{\Gamma(\pi\eta)} &=& 0.35\pm0.16,\\
\frac{\Gamma(K\bar{K})}{\Gamma(\pi\eta)} &=& 0.88\pm0.23,\\
\frac{\Gamma(\omega\pi\pi)}{\Gamma(\pi\eta)} &=& 10.7\pm2.3,
\end{eqnarray}
  together with the assumption that these are the only modes to calculate the branching ratios. The $a_0^+(1450)$ is allowed to be off-shell by the width.
The $a_0^+(1450)$ has mass $1474$~MeV and is unstable. The $a_0^+(1450)$ has spin $0$, charge $1$ and is colour neutral.
 The $a_0^+(1450)$ is a meson and is from the $1^3P_0$ multiplet.The $a_0^+(1450)$ has width $265$~MeV. The lower limit on the mass of the particle is $265$~MeV and the upper limit is $265$~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 10211.
