Measurement of the CKM angle γ 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+→DK+, B0d→DK∗0, Bd→DK+π− and B+→DK+π+π− tree-level decays. In addition, results from a time-dependent analysis of B0s→D∓sK± decays are included. The combination yields γ=(72.2+6.8−7.3)∘, 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.
