Determining the CKM angle $\gamma$ with $B_c$ decays

We consider the possibility of extracting the CKM angle $\gamma$ with $B_c$ decays. The modes $B_c^{\pm }\to (D^0)D_s^{\pm }\to (K^{*+}{K}^{-})D_s^{\pm }$ and $B_c^{\pm }\to ({\overline{D}}^0)D_s^{\pm }\to (K^{*+}{K}^{-})D_s^{\pm }$ are found to be well suited for the extraction of $\gamma$. Since a large number of $B_c$ mesons are expected to be produced at the Large Hadron Collider, it would be very interesting to explore the determination of $\gamma$ with these modes.
