Abstract
Several methods have been devised for measuring the weak phase gamma using decays of the type B-->DK. It is shown that these and other direct CP-viola tion measurements suffer from discrete ambiguity which is at least 8-fold. Combining two measurement methods helps reduce-the ambiguity and the experi mental error. The measurement sensitivity and new physics discovery potenti al are estimated using a full Monte Carlo detector simulation with realisti c background estimates, giving particular consideration to ambiguities.
