Using 20.3 fb^{-1} of e^{+}e^{-} annihilation data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we report the first observation of the semileptonic decays D^{0}→K^{-}ωe^{+}ν_{e} and D^{+}→K_{S}^{0}ωe^{+}ν_{e} with significances of 8.0σ and 5.8σ, respectively. Their decay branching fractions …
