Abstract
We report on the search for the rare decays B+-> (D(*)+KS0) in approximately 226 x Upsilon(4S)-> B (B) over bar decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We do not observe any significant signal and we set 90% confidence-level upper limits on the branching fractions, B(B+-> (D+K0))< 0.5 x 10(-5) and B(B+-> (D*+K0))< 0.9 x 10(-5).
