\title{\boldmath{ $D_s^+$}\ \ \ \ \ \ \ $****$}
\maketitle
The $D_s^+$ is the lightest meson containing a charm and a strange quark, it decays weakly. The mass and lifetime are well measured but the decay modes aren't as well known. The mass and lifetime are taken from \cite{Yao:2006px}. We take the majority of the decay modes from \cite{Yao:2006px} together with the addition of some additional modes, about 10\% of the branching ratio, to saturate the decays.


The $D_s^+$ has mass $1968.2$~MeV and is unstable. The $D_s^+$ has spin $0$, charge $1$ and is colour neutral.
 The $D_s^+$ 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 $0.00015$~m. The PDG code is 431.
