Abstract

A combination of three LHCb measurements of the CKM angle γ is presented. The decays B ^±→DK ^± and B ^±→Dπ ^± are used, where D denotes an admixture of D ⁰ and D-0 mesons, decaying into K ⁺K ^-, π ⁺π ^-, K ^±π ^∓, K ^±π ^∓π ^±π ^∓, KS0π+π-, or KS0K+K- final states. All measurements use a dataset corresponding to 1.0 fb ^-1 of integrated luminosity. Combining results from B ^±→DK ^± decays alone a best-fit value of γ=72.0° is found, and confidence intervals are setγ∈[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 intervalsγ∈[7.4,99.2]°∪[167.9,176.4]°at 68% CL are set, without constraint at 95% CL. The combination of results from B ^±→DK ^± and B ^±→Dπ ^± decays gives a best-fit value of γ=72.6° and the confidence intervalsγ∈[55.4,82.3]°at 68% CL,γ∈[40.2,92.7]°at 95% CL are set. All values are expressed modulo 180°, and are obtained taking into account the effect of D ⁰-D-0 mixing.
