| Abstract: | We search for the exclusive decays B -> (K+,KS,K*+,K*0)nu nubar in a sample of 9.7 million charged and neutral B meson decays recorded by the CLEO detector at the Y(4S)resonance. The technique was one of full event reconstruction where after electing a signal B candidate the remainder of the event is required to be consistent with a hadronic B -> D(*)(npi) decay. No signals were observed so 90% confidence level upper limits were set at: B(B+ -> K+ nu nubar) < 6.1 ? 10?4,
B(B0 -> KS nu nubar) < 2.3 ? 10?3,
B(B+ -> K*+ nu nubar) < 2.0 ? 10?3,
and B(B0 -> K*0 nu nubar) < 2.6 ? 10?3. |
