Abstract

We present a search for the decays B -> K-*nu(nu)overbar using 454x10(6)B(B)overbar pairs collected at the Upsilon(4S) resonance with the BABAR detector at the SLAC PEP-II B-Factory. We first select an event sample where one B is reconstructed in a semileptonic or hadronic mode with one charmed meson. The remaining particles in the event are then examined to search for a B -> K-*nu(nu)overbar decay. The charged K-* is reconstructed as K*+-> K-S(0)pi(+) or K*+-> K+pi(0); the neutral K-* is identified in K-*0 -> K+pi(-) mode. We establish upper limits at 90% confidence level of B(B+-> K*+nu(nu)overbar>)< 8x10(-5), B(B-0 -> K-*0 nu(nu)overbar)< 12x10(-5), and B(B -> K-*nu(nu)overbar)< 8x10(-5).
