\title{\boldmath{ $\rho^-(1700)$}\ \ \ \ \ \ \ $***$}
\maketitle
The $\rho^-(1700)$ is the charged member of the isospin triplet in the $1^3D_1$ multiplet. It mass and width are not well measured, the values are taken from \cite{Yao:2006px}. The branching ratios are problematic. A large number of modes have been observed and the consensus seems to be that the four pion mode is dominant with a sub-dominant two pion mode and a few other modes.

  In order to obtain the branching ratios we have used values for the ratio of branching ratios from \cite{Yao:2006px}, to obtain these ratios. The composition of the four pion mode was then taken from \cite{Abele:2001pv} . The values we used were
\begin{eqnarray}
\frac{\Gamma(2\pi)}{\Gamma(4\pi)} = 0.16,\\
\frac{\Gamma(\eta\rho)}{\Gamma(4\pi)} = 0.123,\\
\frac{\Gamma(K^*K)}{\Gamma(4\pi)} = 0.048,\\
\frac{\Gamma(K\bar{K})}{\Gamma(K^*K)} = 0.052.
\end{eqnarray}
  In addition we ignored the $e^+e^-$ and $\pi\omega$ modes which should have small branching ratios.

  The $\rho^-(1700)$ is allowed to be off-shell by the twice the width.
The $\rho^-(1700)$ has mass $1720$~MeV and is unstable. The $\rho^-(1700)$ has spin $1$, charge $-1$ and is colour neutral.
 The $\rho^-(1700)$ is a meson and is from the $1^3D_1$ multiplet.The $\rho^-(1700)$ has width $250$~MeV. The lower limit on the mass of the particle is $500$~MeV and the upper limit is $500$~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 -30213.
