\title{\boldmath{ $K^-$}\ \ \ \ \ \ \ $*****$}
\maketitle
The \cite{Yao:2006px} is the charged member of the strange isospin doublet from the $1^1S_0$. The charged kaon is stable on collider time-scales but the modes are included for completeness. The properties and modes are taken from \cite{Yao:2006px} with minor adjustments to the branching ratios to ensure they sum to one.
The $K^-$ has mass $493.677$~MeV and is stable. The $K^-$ has spin $0$, charge $-1$ and is colour neutral.
 The $K^-$ is a meson and is from the $1^1S_0$ multiplet.The properties of the particle and its antiparticle are taken to be charge-conjugate to each other.
 The decay length is $3.713$~m. The PDG code is -321.
