摘要：
The Gronau-London-Wyler method extracts the Cabibbo-Kobayashi-Maskawa angle gamma by measuring B+/- decay rates involving D-0/<(D)over bar(0)> mesons. CP violation can be greatly enhanced for decays to final states common to both D-0 and <(D)over bar(0)> that are not CP eigenstates. Large asymmetries are possible for final states f such that D-0 --> f is doubly Cabibbo suppressed while <(D)over bar(0)> --> f is Cabibbo allowed. The measurement of interference effects in such modes allows the clean extraction of gamma.
