Abstract
We present a study of the decays B0-->D0K*0 and B0-->D[over-bar] 0K*0 with K*0-->K+π-. The D0 and the D[over-bar] 0 mesons are reconstructed in the final states f=K+pi-, K+pi-pi0, K+pi-pi+pi-, and their charge conjugates. Using a sample of 465×106 BB[over-bar] pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC, we measure the ratio RADS≡[Γ(B[over-bar] 0-->[f]DK[over-bar] *0)+Γ(B0 -->[f[over-bar] ]DK*0)]/[Γ(B[over-bar] 0-->[f[over-bar] ]DK[over-bar] *0)+Γ(B0-->[f]DK*0)] for the three final states. We do not find significant evidence for a signal and set the following limits at 95% probability: RADS(Kpi)<0.244, RADS(Kpipi0)<0.181, and RADS(Kπππ)<0.391. From the combination of these three results, we find that the ratio rS between the b-->u and the b→c amplitudes lies in the range [0.07,0.41] at 95% probability.
