Description
Dalitz plot analyses of $D \to K_S^0 h h$ ($D = D^0$ or $\bar{D}^0$, $h = K$ or $\pi$) decays following $B \to D^{(*)} K^{(*)}$ decay provide sensitive measurements of CP-violating angle $\phi_3$. We present the first measurement of the CP-violating angle $\phi_3$ using a model-dependent Dalitz plot analysis of $B \to D K$, $D \to K_S^0 K^{\pm} \pi^{\mp}$ decays, and unique model-independent Dalitz plot analysis of $B^0 \to D K^{*}(892)^0$ decays followed by $D \to K_S^0 \pi^+ \pi^-$ and $K^{*}(892)^0 \to K^+ \pi^-$. These measurements use a full data set of $711 fb^{-1}$ collected at the $\Upsilon(4S)$ resonance by the Belle detector at the KEKB collider.
