Description
This report presents precision measurements of the total cross section for $e^+e^-$ annihilation into hadrons, performed with the KEDR detector at the VEPP-4M collider. The KEDR collaboration has measured the $R$ values at 22 center-of-mass energies between 1.84 and 3.72 GeV with the highest accuracy achieved to date. In addition, the energy region from 4.56 to 6.96 GeV was scanned at 17 points, corresponding to an integrated luminosity of approximately 13.7 pb$^{-1}$. The results of this analysis are reported and discussed.
