Measurement of the Total Cross Section for Hadronic Production by e+e- Annihilation at Energies between 2.6-5 Gev

J. Z. Bai

Using the upgraded Beijing Spectrometer (BESII), we have measured the total cross section for $e^{+}{e}^{-}$ annihilation into hadronic final states at center-of-mass energies of 2.6, 3.…
