Abstract

We search for the decay of the B meson into a pair of leptons in the suppressed channels B →e e , B →μ μ and in the lepton number violating channel B →e μ in a sample of 9.7×10 BB̄ pairs recorded by CLEO detector. No signal is found, and the following upper limits on the branching fractions are established: B(B →e e )<8.3×10 , B(B →μ μ )<6.1×10 , B(B →e μ )<15×10 at 90% confidence level. A new lower limit on the Pati-Salam leptoquark mass M >27 TeV is established at 90% confidence level. © 2000 The American Physical Society. 0 0 + - 0 + - 0 ± ∓ 6 0 + - -7 0 + - -7 0 ± ∓ -7 LQ
