Measurement of the Branching Fractions and CP Asymmetries of B- --> D0(CP)K- Decays with the BABAR Detector

Creators

Description

The authors have reconstructed B- --> D0K- decays with D0 mesons decaying to non-CP (K-π+), CD-even (K-K+, π-π+) and CP-odd (K0sπ0) eigenstates. They have measured the CP asymmetries ACP+ = 0.40 ± 0.15(stat) ± 0.08(syst), ACP- = 0.21 ± 0.17(stat) ± 0.07(syst), and the double ratio of branching fractions R+ = 0.87 ± 0.14(stat) ± 0.06(syst), R- = 0.80 ± 0.14(stat) ± 0.08(syst). These results improve the previous existing measurements from BABAR. All results presented in this document are preliminary
