We present a measurement of the branching fraction for the decay B--->(DK*-)-K-0 using a sample of approximately 86x10(6) B (B) over bar pairs collected by the BABAR detector from e(+)e(-) collisions near the Y(4S) resonance. The D-0 is detected through its decays to K(-)pi(+), K(-)pi(+)pi(0), and K(-)pi(+)pi(-)pi(+), and the K*- through its decay to K(S)(0)pi(-). We measure the branching fraction to be B(B--->(DK*-)-K-0)=[6.3+/-0.7(stat)+/-0.5(syst)]x10(-4).

Abstract
We present a measurement of the branching fraction for the decay B--->(DK*-)-K-0 using a sample of approximately 86x10(6) B (B) over bar pairs collected by the BABAR detector from e(+)e(-) collisions near the Y(4S) resonance. The D-0 is detected through its decays to K(-)pi(+), K(-)pi(+)pi(0), and K(-)pi(+)pi(-)pi(+), and the K*- through its decay to K(S)(0)pi(-). We measure the branching fraction to be B(B--->(DK*-)-K-0)=[6.3+/-0.7(stat)+/-0.5(syst)]x10(-4).File in questo prodotto:
