\maketitle
The charm quark is the isospin=$1/2$ second generation quark. The physical mass is at the centre of the range quoted in \cite{Yao:2006px} and is only used as a coupling while the constituent mass is used kinematically.
The $c$ has mass $1250$~MeV and is stable. The $c$ has spin $1/2$, charge $2/3$ and is in a colour triplet.
 The $c$ is a quark.
The particle is a constituent of the hadrons and the constituent mass is 1600 MeV. The properties of the particle and its antiparticle are taken to be charge-conjugate to each other.
 The PDG code is 4.
There are no decay modes for the $c$.



 There is no mass generator for the $c$.
 There is no width generator for the $c$.
