We report results from the first measurements of the CKM angle γ using
B→DK decays with the LHCb experiment. Three well established
methods are used to extract the CP observables. The updated measurement of
γ in the three-body D0 Dalitz space results in γ=(57±16)∘. When combining the observables from all \bdk studies, the best fit
value for γ∈[0,180]∘ is γ=67.2∘ with γ∈[55.1,79.1]∘ at 68%CL and γ∈[43.9,89.5]∘ at 95%CL. This
represents the most precise γ values directly measured by a single
experiment. Furthermore, a new time-dependent approach using Bs​→Ds​K decays is used for the first time to measure CP observables and future
prospects for γ at LHCb are given.Comment: 4 pages, 7 figures. Proceedings of the LHCP 2013 conferenc
