\title{\boldmath{ $\kappa^+$}\ \ \ \ \ \ \ $**$}
\maketitle
The $\kappa^+$ is a light scalar meson close to the $K\pi$ threshold. Its existance is controversial and it is only included to represent an $s$-wave $K\pi$ state in some hadronic matrix elements. The lower limit on the off-shellness is taken above the $K\pi$ threshold and the upper limit is set to twice the width due to the large width. 
The $\kappa^+$ has mass $841$~MeV and is unstable. The $\kappa^+$ has spin $0$, charge $1$ and is colour neutral.
 The $\kappa^+$ is a mesonThe $\kappa^+$ has width $618$~MeV. The lower limit on the mass of the particle is $207$~MeV and the upper limit is $1236$~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 9000321.
