Determining the CKM angle gamma with B_c decays

Abstract

We consider the possibility of extracting the CKM angle $\gamma$ with $B_c$ decays. The modes $B_c^{\pm }\to (D^0)D_s^{\pm }\to (K^{\ast +}{K}^{-})D_s^{\pm }$ and $B_c^{\pm }\to ({\bar{D}}^0)D_s^{\pm }\to (K^{\ast +}{K}^{-})D_s^{\pm }$ 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.
