  • — The review presents the experiments performed with the KEDR detector at the collider VEPP-4M in the energy range of = 1.84–3.88 GeV. The cross section of annihilation to hadrons was measured at 22 points of this range and the search for narrow resonances was conducted below 3.1 GeV. The masses of and mesons were measured with a record accuracy better than ; their partial and total widths were determined. Measurements of the tau lepton mass and masses of charged and neutral  mesons were performed with high precision. The measurements of the parameters are discussed, and attention is drawn to some inconsistency of the procedure employed by the Particle Data Group for determining its parameters.
