Abstract

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