摘要

Using ee annihilation data collected by the CLEO II detector at CESR, we have observed the decay D s → ωπ. This final state may be produced through the annihilation decay of the D s , or through final state interactions. We find a branching ratio of Γ(D s → ωπ)/Γ(D s → ηπ) = 0.16 ± 0.04 ± 0.03, where the first error is statistical and the second is systematic. PACS numbers: 13.25.Ft, 14.40.Lb
