We present a search for the decays B0e+e-, B0μ+μ-, and B0e±μ using data collected with the BABAR detector at the PEP-II e+e- collider at SLAC. Using a data set corresponding to 384×106 BB̅ pairs, we do not find evidence of any of the three decay modes. We obtain upper limit on the branching fractions, at 90% confidence level, of B(B0e+e-)<11.3×10-8, B(B0μ+μ-)<5.2×10-8, and B(B0e±μ)<9.2×10-8.
