Book excerpt: The authors have reconstructed B[sup -] --> D[sup 0]K[sup -] decays with D[sup 0] mesons decaying to non-CP (K[sup -][pi][sup +]), CD-even (K[sup -]K[sup +], [pi][sup -][pi][sup +]) and CP-odd (K[sup 0][sub s][pi][sup 0]) 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[sub +] = 0.87 [+-] 0.14(stat) [+-] 0.06(syst), R[sub -] = 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.
