\title{\boldmath{ $\chi_{c0}(1P)$}\ \ \ \ \ \ \ $***$}
\maketitle
The $\chi_{c0}(1P)$ is the lightest scalar $c\bar{c}$ state. The mass and width are measured and are taken from \cite{Yao:2006px}. The branching ratios for a number of modes are measured however the sum of the measured modes is insufficient to saturate the total width and therefore the remainder is modelled using parton modes. The $\chi_{c0}(1P)$ is allowed to be off-shell by ten times the width.
The $\chi_{c0}(1P)$ has mass $3414.76$~MeV and is unstable. The $\chi_{c0}(1P)$ has spin $0$, charge $0$ and is colour neutral.
 The $\chi_{c0}(1P)$ is a meson and is from the $1^3P_0$ multiplet.The $\chi_{c0}(1P)$ has width $10.4$~MeV. The lower limit on the mass of the particle is $104$~MeV and the upper limit is $104$~MeV. These are the deviations from the on-shell value. The branching ratios are fixed.
The properties of the particle and its antiparticle are taken to be charge-conjugate to each other.
 The PDG code is 10441.
