Abstract
Using data collected near the Ds*+ Ds- peak production energy Ecm=4170 MeV by the CLEO-c detector, we search for Ds+ exclusive hadronic decays involving omega. We find B(Ds+ -> pi+ omega) = (0.21 +- 0.09 +- 0.01)%, B(Ds+ -> pi+ pi0 omega) = (2.78 +- 0.65 +- 0.25)%, B(Ds+ -> pi+ pi+ pi- omega) = (1.58 +- 0.45 +- 0.09)%, B(Ds+ -> pi+ eta omega) = (0.85 +- 0.54 +- 0.06)%, B(Ds+ -> K+ omega) <0.24%, B(Ds+ -> K+ pi0 omega) <0.82%, B(Ds+ -> K+ pi+ pi- omega) <0.54%, and B(Ds+ -> K+ eta omega) <0.79%. The upper limits are at 90% confidence level.
