Abstract

We report a search for the decays B0→Ds-Ds+, B0→Ds*-Ds+, and B0→Ds*-Ds*+ in a sample of 232×106 Υ(4S) decays to BB̄ pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e- storage ring. We find no significant signal and set upper bounds for the branching fractions: B(B0→Ds-Ds+)<1.0×10-4, B(B0→Ds*-Ds+)<1.3×10-4, and B(B0→Ds*-Ds*+) <2.4×10-4 at 90% confidence level. © 2005 The American Physical Society.
