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 BB̄ 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 M_LQ>27 TeV is established at 90% confidence level.

N2 - 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 BB̄ 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.
