Book excerpt: Using 1.3 fb-̂1 of data from p-pbar collisions at sqrt{s}=1.96 TeV collected with the CDF II detector at the Fermilab Tevatron, we have measured the relative branching ratio BR(B-̂ -> D0̂ K-̂)/BR(B-̂ -> D0̂ pi-̂) and its charge conjugate in the D0̂ flavor decay mode D0̂_f -> K-̂pi+̂ and the CP-even decay modes D0̂ -> K-̂K+̂ and D0̂ -> pi-̂pi+̂. From these measurements, we derive: R = (7.99 +- 0.33(stat.) +- 0.38(sys.)) %, R_{CP+} = 1.15 +- 0.17(stat.) +- 0.02(sys.), A_{CP+} = 0.10 +- 0.15(stat.) +- 0.02(sys.). These values are consistent with Standard Model expectations.
