Observation of the decay D-s(+)->omega pi(+)

Abstract

Using e(+)e(-) annihilation data collected by the CLEO II detector at CESR, we have observed the decay D-s(+)-->omega pi(+). This final state may be produced through the annihilation decay df the D-s(+), or through final state interactions. We find a branching ratio of Gamma(D-s(+)-->omega pi(+))/Gamma(D-s(+)-->eta pi(+)) = 0.16+/-0.04+/-0.03, where the first error is statistical and the second is systematic.
