DOIAbstract
See paper for full list of authorsA combination of three LHCb measurements of the CKM angle \gamma\ is presented. The decays B->DK and B->D\pi\ are used, where D denotes an admixture of D0 and D0-bar mesons, decaying into KK, \pi\pi, K\pi, K\pi\pi\pi, KS\pi\pi, or KSKK final states. Combining results from B->DK decays alone a best-fit value of \gamma=70.5 deg is found, and confidence intervals are set \gamma\ in [54.9, 85.4] deg at 68% CL, \gamma\ in [41.8, 98.1] deg at 95% CL. The best-fit value of \gamma\ found from a combination of results from B->D\pi\ decays alone, is \gamma=97.1 deg, and the confidence intervals \gamma\ in [8.8, 43.8] deg or [79.3, 137.4] deg or [165.8, 177.1] deg at 68% CL are set, without constraint at 95% CL.
