Phys. Rev. Lett. 78, 3257–3260 (1997)Enhanced CP Violation with B→KD0(D̅ 0) Modes and Extraction of the Cabibbo-Kobayashi-Maskawa Angle γReceived 20 December 1996; published in the issue dated 28 April 1997 The Gronau-London-Wyler method extracts the Cabibbo-Kobayashi-Maskawa angle γ by measuring B± decay rates involving D0/D̅ 0 mesons. CP violation can be greatly enhanced for decays to final states common to both D0 and D̅ 0 that are not CP eigenstates. Large asymmetries are possible for final states f such that D0→f is doubly Cabibbo suppressed while D̅ 0→f is Cabibbo allowed. The measurement of interference effects in such modes allows the clean extraction of γ. © 1997 The American Physical Society URL:
