A Study of {bar B}{sup 0} --> D(*){sup 0} {bar K}(*){sup 0} Decays
- SLAC
The authors presented evidence for the decay {bar B}{sup 0} --> D*{sup 0}{bar K}{sup 0} as well as new measurements of the branching fractions for the decays {bar B}{sup 0} --> D{sup 0}{bar K}{sup 0} and D{sup 0}{bar K}*{sup 0}. Their measurements are in agreement with the expectation derived from a cited reference and with previous measurements. They use the central value of their measurement for B({bar B}{sup 0} --> {bar D}{sup 0}K*{sup 0}) and obtain {tau} < 0.8 at the 90% C.L. from a central value of {tau} = 0.4 {+-} 0.2 (stat.) {+-} 0.2 (syst.). The main contribution to the systematic uncertainty is from the estimated peaking background since most systematic uncertainties on the branching fractions cancel in the ratio.
