Measurement of the CKM angle [gamma] from a combination of LHCb results

Abstract A combination of measurements sensitive to the CKM angle γ from LHCb is performed. The inputs are from analyses of time-integrated B + [arrow right] DK +, B 0 [arrow right] DK 0, B 0 [arrow right] DK +[pi]- and B + [arrow right] DK +[pi]+[pi]- tree-level decays. In addition, results from a...

Zusammenfassung:	Abstract A combination of measurements sensitive to the CKM angle γ from LHCb is performed. The inputs are from analyses of time-integrated B + [arrow right] DK +, B 0 [arrow right] DK 0, B 0 [arrow right] DK +[pi]- and B + [arrow right] DK +[pi]+[pi]- tree-level decays. In addition, results from a time-dependent analysis of B s 0 [arrow right]D s K ± decays are included. The combination yields γ=(72.2 -7.3 +6.8 )°, where the uncertainty includes systematic effects. The 95.5% confidence level interval is determined to be γ [55.9, 85.2]°. A second combination is investigated, also including measurements from B + [arrow right] D[pi]+ and B + [arrow right] D[pi]+[pi]-[pi]+ decays, which yields compatible results.
