Measuring $\gamma$ at LHCb with $B^{+-} \to (\overline{D^{0}}/D^{0})(K\pi,KK,\pi\pi) K^{+-}$ Decays

A method of extracting the CKM angle gamma from the decay rates of the processes B+- -> (D0/D~0)(Kpi,KK,pipi) K+- is presented. Knowledge of the relative D0/D~0 two-body branching fractions and the selection efficiencies are used to reduce the number of unknown parameters. From one nominal year of LHCb data-taking (2fb-1 integrated luminosity), a precision on gamma in the range 8.2-9.6 degrees is expected, depending on the value of the unknown strong phase in the Kpi decay.
