Açıklama

A search has been performed for the semileptonic decays ${D}^{0}\to {K}_{S}^{0}{K}^{-}{e}^{+}{\nu }_{e}$, ${D}^{+}\to {K}_{S}^{0}{K}_{S}^{0}{e}^{+}{\nu }_{e}$, and ${D}^{+}\to {K}^{+}{K}^{-}{e}^{+}{\nu }_{e}$, using $7.9\text{}\text{}{\mathrm{fb}}^{-1}$ of ${e}^{+}{e}^{-}$ annihilation data collected at the center-of-mass energy $\sqrt{s}=3.773\text{}\text{}\mathrm{GeV}$ by the BESIII detector operating at the BEPCII collider. No significant signals are observed, and upper limits are set at the 90% confidence level of $2.13×{10}^{-5}$, $1.54×{10}^{-5}$, and $2.10×{10}^{-5}$ for the branching fractions of ${D}^{0}\to {K}_{S}^{0}{K}^{-}{e}^{+}{\nu }_{e}$, ${D}^{+}\to {K}_{S}^{0}{K}_{S}^{0}{e}^{+}{\nu }_{e}$, and ${D}^{+}\to {K}^{+}{K}^{-}{e}^{+}{\nu }_{e}$, respectively.
