\title{\boldmath{ $\pi^+(1300)$}\ \ \ \ \ \ \ $***$}
\maketitle
The mass and width of the $\pi^+(1300)$ are not accurately measured. We have taken the mass from \cite{Yao:2006px} together with the central value of the range given from the width. We have also assumed that the $\rho\pi$ decay modes is dominant, in fact this is the only mode we have included. The $\pi^+(1300)$ is allowed to be off-shell by the width.
The $\pi^+(1300)$ has mass $1300$~MeV and is unstable. The $\pi^+(1300)$ has spin $0$, charge $1$ and is colour neutral.
 The $\pi^+(1300)$ is a meson and is from the $2^1S_0$ multiplet.The $\pi^+(1300)$ has width $400$~MeV. The lower limit on the mass of the particle is $400$~MeV and the upper limit is $400$~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 100211.
