  "abstract": "We search for the decays of the $B^0$ meson into $e^+e^-$, $\\mu^+\\mu^-$ $e^{\\pm}\\mu^{\\mp}$ pairs in a sample of $9.7\\times 10^6$ $B{\\bar B}$ pairs recorded by CLEO detector. No signal is found, and the following upper limits on the corresponding branching fractions are established: $<8.3\\times 10^{-7}$, $<6.1\\times 10^{-7}$, $< 15\\times 10^{-7}$ at 90% confidence level. A new lower limit on the Pati-Salam leptoquark mass $M_{LQ}>27$ TeV is established at 90% confidence level.",
