Abstract

We search for the decay of the (Formula presented) meson into a pair of leptons in the suppressed channels (Formula presented) (Formula presented) and in the lepton number violating channel (Formula presented) in a sample of (Formula presented) pairs recorded by CLEO detector. No signal is found, and the following upper limits on the branching fractions are established: (Formula presented) (Formula presented) (Formula presented) at 90% confidence level. A new lower limit on the Pati-Salam leptoquark mass (Formula presented) is established at 90% confidence level. © 2000 The American Physical Society.
