The authors present a search for the decays B{sup 0} {yields} e{sup +}e{sup -}, B{sup 0} {yields} {mu}{sup +}{mu}{sup -} and B{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}} using data collected with the BABAR detector at the PEP-II e{sup +}e{sup -} collider at SLAC. Using a dataset corresponding to 384 x 10{sup 6} B{bar B} pairs, they do not find evidence of any of the three decay modes. They obtain upper limit on the branching fractions, at 90% confidence level, of {Beta}(B{sup 0} {yields} e{sup +}e{sup -}) < 11.3 x 10{sup -8}, {Beta}(B{sup 0} {yields} {mu}{sup +}{mu}{sup -}) < 5.2 x 10{sup -8}, and {Beta}(B{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}}) < 9.2 x 10{sup -8}.
