Book Description
The authors have reconstructed B− --> D°K− decays with D° mesons decaying to non-CP (K−?), CD-even (K−K+,?−?+) and CP-odd (K°{sub s}?°) eigenstates. They have measured the CP asymmetries A{sub CP{sup +}} = 0.40 ± 0.15(stat) ± 0.08(syst), A{sup CP{sup -}} = 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.

Book Description
The primary goals of the BABAR experiment are the detection of CP violation (CPV) in the B meson system, the precise measurement of some of the elements of the CKM matrix and the measurement of the rates of rare B meson decays. At present, BABAR has achieved major successes: (1) the discovery, in neutral B decays, of direct and mixing-induced CP violation; (2) accurate measurements of the magnitudes of the CKM matrix elements.

Book Description
We present measurements of branching fractions and CP-violating asymmetries for neutral B meson decays to two-body final states of charged pions and kaons. The results are obtained from a data sample of about 88 million[Upsilon](4S)[yields] B[bar B] decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. From a time-independent fit we measure the charge-averaged branching fractions[Beta](B[sup 0][yields][pi][sup+][pi][sup -])= (4.7[+-] 0.6[+-] 0.2) x 10[sup -6] and[Beta](B[sup 0][yields] K[sup+][pi][sup -])= (17.9[+-] 0.9[+-] 0.7) x 10[sup -6], where the first uncertainty is statistical and the second is systematic; the 90% confidence level upper limit[Beta](B[sup 0][yields] K[sup+]K[sup -])
