Search for the decay of a B0 or B̄0 meson to K̄*0K0 or K*0K̄0
We present a search for the decay of a B0 or B̄0 meson to a K̄*0K0 or K*0K̄0 final state, using a sample of approximately 232×106 BB̄ events collected with the BABAR detector at the PEP-II asymmetric energy e+e- collider at SLAC. The measured branching fraction is B(B0→K̄*0K0)+B(B0→K*0K̄0)=(0.2-0.8-...

| description | We present a search for the decay of a B0 or B̄0 meson to a K̄*0K0 or K*0K̄0 final state, using a sample of approximately 232×106 BB̄ events collected with the BABAR detector at the PEP-II asymmetric energy e+e- collider at SLAC. The measured branching fraction is B(B0→K̄*0K0)+B(B0→K*0K̄0)=(0.2-0.8- 0.3+0.9+0.1)×10-6. We obtain the following upper limit for the branching fraction at 90% confidence level: B(B0→K̄*0K0) +B(B0→K*0K̄0)<1.9×10-6. We use our result to constrain the standard model prediction for the deviation of the CP asymmetry in B0→K0 from sin2β. © 2006 The American Physical Society. |
