Abstract

We have searched for [Special characters omitted.] resonance production using data taking by CLEO III detector and set an upper limit for such a cross section to be on the order of 0.05-0.10 units of R in 95% confidence level in the scanning range at Center Mass of Energies from 11.230 to 11.382 GeV. The measurement of R = σ( e + e - [arrow right] hadrons)/σ( e + e - [arrow right] μ + μ - ) has been made in this scan range as well. The measured R value near Λ b threshold is R = 4.01 ± 0.15
