\title{\boldmath{ $\Lambda_c^+$}\ \ \ \ \ \ \ $****$}
\maketitle
The $\Lambda_c^+$ is the lightest baryon containing a charm quark. The mass and width have been measured with reasonable accuracy and are taken from \cite{Yao:2006px}. A number of decay modes have been observed, however the branching ratios are only known relative to the $pK^-\pi^+$ mode. We choose to use the PDG value for the branching ratio of this mode. The inclusive decay modes are taken from \cite{Yao:2006px}, with some modes added from \cite{Korner:1992wi} . The rest of the decays are simulated using partonic decays with the inclusive leptonic rate taken from \cite{Yao:2006px}. The hadronic parton modes are assumed to be in the ratio 3:1 for the direct channels and the colour exchanged modes. The rates for the quarks produced at the weak vertex are assumed to be given by the CKM factors. No partonic semi-leptonic decays are included due to problems with momentum reshuffling in the cluster model. Multi-body decays of the hadronic state are included instead.
The $\Lambda_c^+$ has mass $2286.46$~MeV and is unstable. The $\Lambda_c^+$ has spin $1/2$, charge $1$ and is colour neutral.
 The $\Lambda_c^+$ is a baryon and is from the $(56,0^+_0)$ $40$plet.The properties of the particle and its antiparticle are taken to be charge-conjugate to each other.
 The decay length is $5.99\times10^{-5}$~m. The PDG code is 4122.
