Measurement of R Between 2-5 GeV
Abstract
We have obtained measurements of the total cross section for e+e- annihilation into hadronic final states for 6 energy points (2.6, 3.2, 2.4, 3.55, 4.6, and 5.0 GeV) with the upgraded Beijing Spectrometer (BESII). We report preliminary values from this data and outline future plans for a finer scan in the 2-5 GeV energy range.
