\title{\boldmath{ $\pi_2^-(1670)$}\ \ \ \ \ \ \ $****$}
\maketitle
The $\pi_2^-(1670)$ is the charged member of the isospin triplet from the pseudotensor multiplet. It mass and width are accurately measured and the branching ratios for a number of modes are known. The branching ratios in the \cite{Yao:2006px} are constrained to sum to one only include the three pion modes and the $KK^*$ modes. We have therefore rescaled these modes to include the $\omega\rho$ modes. We have included the $f_2\pi$, $\rho\pi$ and $(\pi\pi)_S\pi$ modes which sum to give the total three pion rate in the \cite{Yao:2006px}. We have chosen to interpret the $(\pi\pi)_S\pi$ as $\sigma\pi$ and this is in agreement with the measurement of this mode. We allow the $\pi_2^-(1670)$ to be off-shell by the width due to the large width.
The $\pi_2^-(1670)$ has mass $1672.4$~MeV and is unstable. The $\pi_2^-(1670)$ has spin $2$, charge $-1$ and is colour neutral.
 The $\pi_2^-(1670)$ is a meson and is from the $1^1D_2$ multiplet.The $\pi_2^-(1670)$ has width $259$~MeV. The lower limit on the mass of the particle is $259$~MeV and the upper limit is $259$~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 -10215.
