Abstract
We present a search for the decays B-0 -> e(+)e(-), B-0 ->mu(+)mu(-), and B-0 -> e(+/-)mu(-/+) using data collected with the BABAR detector at the PEP-II e(+)e(-) collider at SLAC. Using a data set corresponding to 384x10(6) B (B) over bar 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(B-0 -> e(+)e(-))<11.3x10(-8), B(B-0 ->mu(+)mu(-))<5.2x10(-8), and B(B-0 -> e(+/-)mu(-/+))<9.2x10(-8).
