Search for the decay of a B{sup 0} or B{sup 0} meson to K*{sup 0}K{sup 0} or K*{sup 0}K{sup 0}
- and others
We present a search for the decay of a B{sup 0} or B{sup 0} meson to a K*{sup 0}K{sup 0} or K*{sup 0}K{sup 0} final state, using a sample of approximately 232x10{sup 6} BB events collected with the BABAR detector at the PEP-II asymmetric energy e{sup +}e{sup -} collider at SLAC. The measured branching fraction is B(B{sup 0}{yields}K*{sup 0}K{sup 0})+B(B{sup 0}{yields}K*{sup 0}K{sup 0})=(0.2{sub -0.8-0.3}{sup +0.9+0.1})x10{sup -}= {sup 6}. We obtain the following upper limit for the branching fraction at 90% confidence level: B(B{sup 0}{yields}K*{sup 0}K{sup 0})+B(B{sup 0}{yields}K*{sup 0}K{sup 0})<1.9x10{sup -6}. We use our result to constrain the standard model prediction for the deviation of the CP asymmetry in B{sup 0}{yields}{phi}K{sup 0} from sin2{beta}.
