Measurement of the branching fractions and CP-asymmetry of B- ->D0(cp)K- decays with the BaBar detector
- SLAC
The authors present a study of B{sup -} {yields} D{sub CP}{sup 0} K{sup -} decays, where D{sub CP}{sup 0} is reconstructed in CP-event channels, based on a sample of 88.8 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II e{sup +}e{sup -} storage ring. They measure the ratio of Cabibbo-suppressed to Cabibbo-favored branching fractions {Beta}(B{sup -} {yields} D{sub CP}{sup 0} K{sup -})/{Beta}(B{sup -} {yields} D{sub CP}{sup 0}{pi}{sup -}) = (8.8 {+-} 1.6(stat) {+-} 0.5(syst)) x 10{sup -2} and the CP asymmetry A{sub CP} = 0.07 {+-} 0.17(stat) {+-} 0.06(syst). The authors also measure {Beta}(B{sup -} {yields} D{sup 0}K{sup -})/{Beta}(B{sup -} {yields} D{sup 0}{pi}{sup -}) = (8.31 {+-} 0.35(stat) {+-} 0.20(syst)) x 10{sup -2} using a sample of 61.0 million B{bar B} pairs.
