Book Description
In this talk the author will discuss the extraction of the CKM angle[gamma] at B-factories through the interference of the subprocesses B[sup[minus]][r-arrow] K[sup[minus]]D[sup 0] and B[sup[minus]][r-arrow] K[sup[minus]][anti D][sup 0]. This seemingly impossible interference may be accomplished by allowing both D[sup 0] and[anti D][sup 0] to decay to a common final state. If only CP eigenstate decay modes of the D are considered, the branching ratio for B[sup[minus]][r-arrow][anti D][sup 0]K[sup[minus]] must be experimentally determined in order to extract[gamma]. He describes why this determination is likely to be experimentally impossible. On the other hand, if more general D decays are considered, the angle[gamma] may then be determined. In fact, it is possible that a reasonable determination of[gamma] may be made with O(10[sup 8]) B's.
