Measurement of $\gamma$ using a $D$ Dalitz analysis of $B^\pm \to D^{(*)} K^{(*)\pm}$ decays

We report on an improved measurement of the Cabibbo-Kobayashi-Maskawa CP-violating phase $\gamma$ through a Dalitz analysis of neutral $D$ decays to $K^0_S \pi^+ \pi^-$ and $K^0_S K^+ K^-$ in the processes $B^\mp \to D K^\mp$, $B^\mp \to D^* K^\mp$ with $D^* \to D \pi^0,D\gamma$, and $B^\mp \to D K^{*\mp}$ with $K^{*\mp} \to K^0_S \pi^\mp$. The analysis is based on a sample of 383 million $B \bar B$ pairs collected by the BaBar detector at the PEP-II asymmetric-energy $e^+e^-$ collider at SLAC.
