摘要：

The existing experimental data on total cross sections for hadron production in e(+)e(-) annihilation in the resonance region root s=3.8-4.8 GeV, usually presented in terms of the parameter R, are critically examined. It is shown that the Crystal Ball and BES measurements are in excellent agreement, and their analysis leads to consistent resonance parameters for the three vector resonances above the D (D) over bar threshold. The results for the widths are found to be considerably different from the presently adopted values, and have much smaller errors.
