摘要

Abstract

The paper is focused on the precise measurements of the total cross section for \({{e}^{ + }}{{e}^{ - }}\) annihilation into hadronic final states at the VEPP-4M collider in Novosibirsk. The KEDR collaboration has published the R values on 22 points in the center-of-mass energy range from 1.84 to 3.72 GeV with the accuracy better than in previous measurements. The energy range between 4.56 and 6.96 GeV was scanned at 17 points with integrated luminosity of about 13.7 pb \(^{{ - 1}}\) and preliminary results of the analysis are presented.
