Resum

A combination of measurements sensitive to the CKM angle γ from LHCb is performed. The inputs are from analyses of time-integrated B+ → DK+, B0 → DK∗0, B0 → DK+π and B+ → DK+π+π tree-level decays. In addition, results from a time-dependent analysis of Bs 0 → 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+ → Dπ+ and B+ → Dπ+ππ+ decays, which yields compatible results.[Figure not available: see fulltext.]
