The data show $b_{1}π$ decay of the spin-exotic states $π_{1}(1600)$ and \ $π_{1}(2000)$. Three isovector $2^{-+}$ states were seen in the $ωρ^{-}$ decay channel. In addition to the well known $π_{2}(1670)$, signals were also observed for $π_{2}(1880)$ and $π_{2}(1970)$.High Energy Physics - Experimenttext
