B0+-, and B0e Search for decays of B0 mesons into pairs of leptons: B0e+e-

We search for the decay of the B0 meson into a pair of leptons in the suppressed channels B0e+e-, B0+- and in the lepton number violating channel B0e in a sample of 9.7106 BB pairs recorded by CLEO detector. No signal is found, and the following upper limits on the branching fractions are established: B(B0e+e-)<8.310-7, B(B0+-)<6.110 -7, B(B0e )<1510-7 at 90% confidence level. A new lower limit on the Pati-Salam leptoquark mass MLQ>27 TeV is established at 90% confidence level. 2000 The American Physical Society.
