\title{\boldmath{ $\Xi_c^0$}\ \ \ \ \ \ \ $***$}
\maketitle
The $\Xi_c^0$ is the neutral $\Xi_c$ member of the lightest $\Xi_c$ multiplet. The mass and lifetime have been measured and are taken from \cite{Yao:2006px}. 

No absolute branching ratio measurements have been made and only a few ratios of branching fractions are known. We have chosen to normalise these inclusive modes to the value of the $\Xi^-\pi^+$ rate from \cite{Korner:1992wi}  and include the observed modes and other modes predicted in \cite{Korner:1992wi} . 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 partonic semi-leptonic modes have been replaced with multi-body modes due to problems with the hadronization of the partonic decays.
The $\Xi_c^0$ has mass $2471$~MeV and is unstable. The $\Xi_c^0$ has spin $1/2$, charge $0$ and is colour neutral.
 The $\Xi_c^0$ 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 $3.36\times10^{-5}$~m. The PDG code is 4132.
