Measurement of the CKM angle γ from a combination of B±→Dh± analyses

# metadata.dc.description.abstract[].value
A combination of three LHCb measurements of the CKM angle γ is presented. The decays B± → D K ± and B± → Dπ± are used, where D denotes an admixture of D0 and D0 mesons, decaying into K + K −, π+π−, K ±π∓, K ±π∓π±π∓, K0 Sπ+π−, or K0 S K + K − final states. All measurements use a dataset corresponding to 1.0 fb−1 of integrated luminosity. Combining results from B± → D K ± decays alone a best-fit value of γ = 72.0◦ is found, and confidence intervals are set γ ∈ [56.4, 86.7] ◦ at 68% CL, γ ∈ [42.6, 99.6] ◦ at 95% CL. The best-fit value of γ found from a combination of results from B± → Dπ± decays alone, is γ = 18.9◦, and the confidence intervals γ ∈ [7.4, 99.2] ◦ ∪ [167.9, 176.4] ◦ at 68% CL are set, without constraint at 95% CL. The combination of results from B± → D K ± and B± → Dπ± decays gives a best-fit value of γ = 72.6◦ and the confidence intervals γ ∈ [55.4, 82.3] ◦ at 68% CL, γ ∈ [40.2, 92.7] ◦ at 95% CL
