\title{\boldmath{ $\Upsilon_2(1D)$}\ \ \ \ \ \ \ $**$}
\maketitle
The $\Upsilon_2(1D)$ has been observed by CLEO, \cite{Bonvicini:2004yj} . The mass is taken from \cite{Yao:2006px}. The width and branching ratios have not been measured and are taken from \cite{Kwong:1988ae} . The $\Upsilon_2(1D)$ is allowed to be off-shell by ten times the width.
The $\Upsilon_2(1D)$ has mass $10161.1$~MeV and is unstable. The $\Upsilon_2(1D)$ has spin $2$, charge $0$ and is colour neutral.
 The $\Upsilon_2(1D)$ is a meson and is from the $1^3D_2$ multiplet.The $\Upsilon_2(1D)$ has width $0.028$~MeV. The lower limit on the mass of the particle is $0.28$~MeV and the upper limit is $0.28$~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 20555.
