Determination of theCPViolation AngleγUsingB→D*VModes

We propose a method to determine the angle $\gamma =\arg \left(V_{\mathrm{ub}}\right)$, using the $B\to D^{*}V$ $({V=K}^{*},\rho )$ modes. The $D^{*}$ is considered to decay to $D\pi$. An interference of the $B\to D^{*0\mathrm{}}V$ and $B\to \overline{D^{*0\mathrm{}}}V$ amplitudes is achieved by looking at a common final state $f$, in the subsequent decays of $D^0/\overline{D^0}$. A detailed analysis of the angular distribution allows determination, not only of $\gamma$ and $|V_{\mathrm{ub}}|$ but also of all of the hadronic amplitudes and strong phases involved. No prior knowledge of doubly Cabibbo suppressed branching ratios of $D$ are required. Large $\mathrm{CP}$ violating asymmetries ( $\sim 30\%$ for $\gamma =30\mathrm{}°$) are possible if $\overline{D^0}\to f$ is doubly Cabibbo suppressed, while $D^0\to f$ is Cabibbo allowed, for decays of $B^{+}$ or $B^0$.
