We propose a new method to extract the CP-violating weak phase (the phase of Vub*) in the CKM paradigm of the standard model, using and decays, where the f's are final states such as , , , etc. We also study the experimental feasibility of our new method. With the possibility of new phases in the CKM matrix, we re-examine some of the previously proposed methods to determine , and find that it would be in principle possible to identify and a new phase angle separately.
