Abstract

A combination of measurements sensitive to the CKM angle γ from LHCb is performed. The inputs are from analyses of time-integrated B+ → D K+, B0 → D K∗0, B0 → D K+ π− and B+ → D K+ π+ π− tree-level decays. In addition, results from a time-dependent analysis of B0s → Ds∓ 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+ → D π+ and B+ → D π+ π− π+ decays, which yields compatible results.
