Abstract

We develop a method to measure the Cabibbo-Kobayashi-Maskawa angle γ without hadronic uncertainties from the analysis of B^±→ K^±D⁰ and K^± D̄⁰ followed by singly Cabibbo-suppressed D decays to non-CP eigenstates, such as K^±K*^∓. This method utilizes the interference between b→cūs and b→uc̄s decays, and we point out several attractive features of it. All the modes that need to be measured for this method are accessible in the present data.
