Discrete Ambiguities in the Measurement of the Weak Phase Gamma

Several methods have been devised for measuring the phase of the Cabibbo-Kobayashi-Maskawa unitarity triangle, using decays of the type B --> DK. It is shown that these and other direct CP-violation measurements suffer from discrete ambiguity which is at least 8-fold. Combining two measurement methods helps reduce the ambiguity and the experimental error. The measurement sensitivity and new physics discovery potential are estimated using a full Monte Carlo detector simulation with realistic background estimates, giving particular consideration to ambiguities.
