Title: A study of b-->c and b-->u Interference in the Decay B- -->[K+ pi-]_DK*-
Authors: The BABAR Collaboration, B. Aubert et al.

\\
Using a sample of 232 x 10^6 Upsilon(4S)--> B B-bar
events collected with the BABAR detector at the PEP-II B-factory
we study the decay B- --> [K+ pi-]_D K*- where the K+ pi- is either
from a Cabibbo-favored D0-bar decay or doubly-suppressed D0 decay.
We measure two observables that are sensitive to the CKM angle gamma;
the ratio R of the charge-averaged branching fractions for the suppressed and
favored decays; and the charge asymmetry A of the suppressed decays:
R=0.046 +/- 0.031(stat.) +/- 0.008(syst.)
A=-0.22 +/- 0.61(stat.) +/- 0.17(syst.).
