\title{\boldmath{ $\psi(3370)$}\ \ \ \ \ \ \ $****$}
\maketitle
The $\psi(3370)$ is the $c\bar{c}$ meson from the third vector multiplet. The state is sufficently heavy to decay to a $D\bar{D}$ but not strongly to any other state. Therefore the dominant decay is to $D\bar{D}$. There is also a leptonic decay. The muon and tau modes are calculated using the decayer and the electron mode for normalization. The strong modes are calculated assuming an equal coupling and using the decayer to calculate the phase-space effects. The $\psi(3370)$ is allowed to be off-shell by ten times the width above the central value but in the lower direction the off-shellness is limited so that the dominant decays is possible.
The $\psi(3370)$ has mass $3771.1$~MeV and is unstable. The $\psi(3370)$ has spin $1$, charge $0$ and is colour neutral.
 The $\psi(3370)$ is a meson and is from the $1^3D_1$ multiplet.The $\psi(3370)$ has width $23$~MeV. The lower limit on the mass of the particle is $31$~MeV and the upper limit is $230$~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 30443.
