Description/Abstract

We present the first search for the decay D^+_{s}\to \omega e^{+}\nu to test the four-quark content of the D^+_{s} and the \omega-\phi mixing model for this decay. We use 586 \mathrm{pb}^{-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 \mathcal{B}(D^+_{s}\to\omega e^+\nu)
