Determination of the CKM-Angle with Tree-Level Processes at LHCb

Recent results on studies sensitive to the CKM-angle are combined to give an overall estimate of the precision expected at LHCb, assuming the detector performance of the DC04 data challenge. A result of 1.9–2.7 ◦ is obtained for 10 fb −1 of data, with the variation arising from the dependence on the physics parameters involved. Brief discussion is given to other, as yet unexplored, methods for improving this precision still further.
