title = "Search for decays of B0 mesons into pairs of leptons: B0↑e+e-, B0→μ+μ-, and B0→e±μ∓",
abstract = "We search for the decay of the B0 meson into a pair of leptons in the suppressed channels B0→e+e-, B0→μ+μ- and in the lepton number violating channel B0→e±μ∓ in a sample of 9.7×106 B{\=B} pairs recorded by CLEO detector. No signal is found, and the following upper limits on the branching fractions are established: B(B0→e+e-)<8.3×10-7, B(B0→μ+μ-)<6.1×10 -7, B(B0→e±μ ∓)<15×10-7 at 90% confidence level. A new lower limit on the Pati-Salam leptoquark mass MLQ>27 TeV is established at 90% confidence level.",
