\title{\boldmath{ $W^+$}\ \ \ \ \ \ \ $*****$}
\maketitle
The $W^+$ is the charged electroweak gauge boson. The mass and width are taken from \cite{Yao:2006px}. The branching ratios are calculated using the decayer together with a factor of $(1+\alpha_S/\pi)$ for the quark modes. The $W^+$ is allowed to be off-shell by ten times the width.
The $W^+$ has mass $80403$~MeV and is unstable. The $W^+$ has spin $1$, charge $1$ and is colour neutral.
 The $W^+$ is a gauge boson.
The $W^+$ has width $2141$~MeV. The lower limit on the mass of the particle is $21410$~MeV and the upper limit is $21410$~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 24.
