Query: Enhanced CP Violation with $B\to K D^0 (\overline D^0)$ Modes and
  Extraction of the CKM Angle gamma   The Gronau-London-Wyler (GLW) method extracts the CKM angle $\gamma$ by
measuring $B^\pm$ decay rates involving $D^0/\overline D^0$ mesons. Since that
method necessitates the interference between two amplitudes that are
significantly different in magnitude, the resulting asymmetries tend to be
small. CP violation can be greatly enhanced for decays to final states that are
common to both D^0 and $\overline D^0$ and that are not CP eigenstates. In
particular, large asymmetries are possible for final states f such that $D^0\to
f$ is doubly Cabibbo suppressed while $\overline D^0\to f$ is Cabibbo allowed.
The measurement of interference effects in two such modes allows the extraction
of $\gamma$ without prior knowledge of $Br(B^-\to K^- \overline D^0)$, which
may be difficult to determine due to backgrounds.
