\title{\boldmath{ ${D'}_1^-$}\ \ \ \ \ \ \ $***$}
\maketitle
here is evidence for the neutral ${D'}^1$ state from both CLEO and BELLE, however only the BELLE result is included in \cite{Yao:2006px}. We include this state with the mass and width taken from \cite{Colangelo:2004vu} , which is the average of the two experimental results. There has only been one observed mode which we assume is the only mode. The lower limit on the off-shell mass is set so that the decay is kinematically allowed and the upper limit is twice the width given the large width. EvtGen takes a similar approach but uses the mass and width from the CLEO results \cite{Anderson:1999wn} .
The ${D'}_1^-$ has mass $2438$~MeV and is unstable. The ${D'}_1^-$ has spin $1$, charge $-1$ and is colour neutral.
 The ${D'}_1^-$ is a meson and is from the $1^3P_1$ multiplet.The ${D'}_1^-$ has width $329$~MeV. The lower limit on the mass of the particle is $250$~MeV and the upper limit is $658$~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 -20413.
