Book Description

The authors present a measurement of the branching fraction for the decay B− → D° K{sup *-} using a sample of approximately 86 million B{bar B} pairs collected by the BABAR detector from ee− collisions near the?(4S) resonance. The D° is detected through its decays to K−?+, K−?+?° and K−?+?−?+, and the K{sup *-} through its decay to K{sub S}°?−. They measure the branching fraction to be?(B− → D°K{sup *-}) = (6.3 ± 0.7(stat.)±0.5(syst.)) x 10−4.
