Abstract

Recent semileptonic D meson decay results are summarized, including the improved measurements of absolute branching fractions for exclusive D0 semileptonic decays into $K^{-}e^{+}\nu$, $\pi^{-}e^{+}\nu$ and $K^{*-}e^{+}\nu$, and the first observation and absolute branching fraction measurement of $D^{0} \to \rho^{-}e^{+}\nu$ with the first CLEO-c data sample.
