Abstract

We develop a method to measure the CKM angle γ\gamma without hadronic uncertainties from the analysis of B±K±D0B^\pm \to K^\pm D^0 and K±\D0barK^\pm \D0bar followed by singly Cabibbo-suppressed DD decays to non CP-eigenstates, such as K±KK^\pm K^{*\mp}. This method utilizes the interference between bcuˉsb\to c\bar u s and bucˉsb\to u\bar c s 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.
