Abstract

We present the first search for the decay Ds+→ωe+ν to test the four-quark content of the Ds+ and the ω- mixing model for this decay. We use 586pb-1 of e+e- collision data collected at a center-of-mass energy of 4170 MeV. We find no evidence of a signal, and set an upper limit on the branching fraction of B(Ds+→ω e+ν)<0.20% at the 90% confidence level.
