Measurement of R between 1.84 and 3.05 GeV at the KEDR detector

Measurement of R between 1.84 and 3.05 GeV at the KEDR detector

Using the KEDR detector at the VEPP-4M e+e− collider, we have determined the values of R at thirteen points of the center-of-mass energy between 1.84 and 3.05 GeV. The achieved accuracy is about or better than 3.9% at most of the energy points with a systematic uncertainty less than 2.4%.
