Abstract

We present evidence for the decay

{A_{2}}^{0} \to ω π^{+} π^{0}

with a branching ratio

\frac{Γ (A_{2} \to ω π π)}{Γ (A_{2} \to ρ π)} = 0.28 \pm 0.09

and for the decay

ω (1675) \to ω π^{+} π^{-}

with a branching ratio

\frac{Γ (ω (1975) \to ω π^{+} π^{-})}{Γ (ω (1675) \to ρ π)} = 0.47 \pm 0.18

. Evidence is given for an intermediate

B (1235) π

state in the

ω (1675)

decay.
