N2 - We present a search for the decay of a B0 or ¯¯¯B0 meson to a ¯¯¯¯K*0K0 or K*0¯¯¯¯K0 final state, using a sample of approximately 232×10 6 B¯¯¯B events collected with the BABAR detector at the PEP-II asymmetric energy e+e− collider at SLAC. The measured branching fraction is B(B0→¯¯¯¯K*0K0)+B(B0→K*0¯¯¯¯K0)=(0.2+0.9+0.1−0.8−0.3)×10−6. We obtain the following upper limit for the branching fraction at 90% confidence level: B(B0→¯¯¯¯K*0K0)+B(B0→K*0¯¯¯¯K0)<1.9×10−6. We use our result to constrain the standard model prediction for the deviation of the CP asymmetry in B0→ϕK0 from sin 2β.
