Abstract

We report on the study of the decay $B^+ \to D^0(\bar{D0}) K^+$ where $D^0$ and $\bar{D0}$ decaying to $K \pi \pi^0$, with the Atwood Dunietz and Soni (ADS) method. We measure the ratios Rads, $R^+$, $R^-$ since the processes $B^+ \to D^0 \bar{K^+}$ and $B^+ \to D^0 K^+$ are proportional to $V_{cb}$ and $V_{ub}$, respectively, are sensitive to $r_B$ and to the weak phase $\gamma$.
