Evidence for theωππDecay Modes of theA2andω(1675)

Abstract

We present evidence for the decay ${A_2}^0\to \omega {\pi }^{+}{\pi }^0$ with a branching ratio $\frac{\Gamma (A_2\to \omega \pi \pi )}{\Gamma (A_2\to \rho \pi )}=0.28\mathrm{}\pm 0.09$ and for the decay $\omega \mathrm{}\left(1675\right)\mathrm{}\to \omega {\pi }^{+}{\pi }^{-}$ with a branching ratio $\frac{\Gamma \left(\omega \mathrm{}\right(1975)\mathrm{}\to \omega {\pi }^{+}{\pi }^{-})}{\Gamma \left(\omega \mathrm{}\right(1675)\mathrm{}\to \rho \pi )}=0.47\mathrm{}\pm 0.18$. Evidence is given for an intermediate $B\left(1235\right)\mathrm{}\pi$ state in the $\omega \mathrm{}\left(1675\right)\mathrm{}$ decay.
