-
Abstract
The result is presented of precise measurement the values of Ruds and R at seven points of the center-of-mass energy between 312 and 372 GeV based on the data collected with the KEDR detector at the VEPP-4M e+e- collider in Novosibirsk. Also present is the preliminary result of determination of the product of the electron partial width by the branching fraction into hadrons of J/ψ resonance.
