New methods for extracting the CKM angle {gamma} using B{sup {+-}} {r_arrow} D{sup 0}K{sup {minus}}; {anti D}{sup 0}K{sup {minus}}

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 ... continued below

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.
