LHCb Sensitivity to $\gamma$ with $B_{s} \to D_{s} K$

The decay channels Bs->DsK and Bs->DsPi can be used to extract the CKM-matrix gamma angle, a parameter of the Standard Model not yet directly measured. The strategy of the LHCb experiment for such a measurement is described. We also outline the event selection criteria, the expected annual yields and background-over-signal B/S ratii, and the expected precision on the CKM gamma measurement.
