Description
We report a search for the decays B- --> D0 K-
and B- --> D*0 K- and their charge conjugates
where the flavor of the neutral D0 meson is ambiguous.
The final state particles for the D0 K- and D*0 K- modes are
[K+ pi-] K- and ([K+ pi-] pi0) K- or ([K+ pi-] gamma) K-
respectively. These decays are sensitive to the CKM angle gamma due to
interference between the b --> c and b --> u amplitude
contributions, which are of the same order and have a relative weak phase
of gamma. This analysis was first suggested by Atwood, Dunietz, and Soni
(ADS). This is an update, using the full BaBar dataset consisting of 467
million B Bbar pairs, of the previous BaBar B- --> D(*)0 K- ADS analysis.
It also includes an analysis of the doubly Cabibbo suppressed decays
B- --> D(*)0 pi- (D0 --> K+ pi-) and their charge conjugates, which are used
as a control sample to test the ADS analysis.
