Contribution

First measurements of specific B- -> D(*)0 K(*)- decay modes related to gamma, utilizing established methods and BABAR data.

Findings

Branching fractions and CP asymmetries measured.

Results constrain the CP angle gamma.

Data supports methods for CP violation analysis.

Abstract

We present measurements of branching fractions and CP asymmetries of several B- -> D(*)0 K(*)- decays, with the D(*)0 decaying to CP-even, CP-odd, and flavor eigenstates, that can constrain the CP angle gamma as well as the amplitude ratio rb=A(B -> u)/A(B -> c), using methods proposed by Gronau, London and Wyler or Atwood, Dunietz and Sony. We use data collected with the BABAR detector at the PEP-II asymmetric energy e+e- collider at SLAC.
