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 $B_c^\pm \to (\bar D^0) D_s^\pm \to (K^{*+}K^-) D_s^\pm$ 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 LHC, it would be very interesting to explore the determination of $\gamma$ with these modes.
