\title{\boldmath{ $\Omega^0_c$}\ \ \ \ \ \ \ $***$}
\maketitle
The lightest $\Omega_c$ state. The mass and liftime have been measured and taken from \cite{Yao:2006px}. No absolute branching ratios have been measured and only a few ratios of branching ratios are known, usually the rate relative to the $\Omega\pi$ mode.

 We therefore include a few of these exclusive modes and model the rest of the decays as partonic decays. The partonic decays are calculated assuming an 8\% branching ratio for the semileptonic decay $c\to s\ell\nu$. The remaining leptonic modes are calculated using the ratio of the CKM matrix elements. The hadronic decays are calculated by including the normal decays and the colour exchanged decays with a factor of $1/3$ the direct decay. The CKM factors are used to calculated the rates for the different quarks produced in the weak decays. The exclusive modes are then subtracted from the relevant partonic mode.
The $\Omega^0_c$ has mass $2697.5$~MeV and is unstable. The $\Omega^0_c$ has spin $1/2$, charge $0$ and is colour neutral.
 The $\Omega^0_c$ 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 $2.1\times10^{-5}$~m. The PDG code is 4332.
