Description

We present the results on the inclusive cross section of e+e- single
photon annihilation into hadrons in the energy range from 1.84 to 3.72 GeV obtained at the KEDR experiment, which include values of the R measurement in 22 points and of leptonic widths of J/psi and psi(2S) mesons. The results are important or determination of the muon anomalous magnetic moment, the fine structure constant at the Z^0 peak, the strong coupling constant as function of energy, and the heavy-quark masses.
