Measurement of the Pion Form Factor in the Energy Range 1.04-1.38 GeV with the CMD-2 Detector

Abstract

The cross section for the process $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}$ is measured in the c.m. energy range 1.04-1.38 GeV from 995 000 selected collinear events including 860000 $e^{+}{e}^{-}$ events, 82000 ${\mu }^{+}{\mu }^{-}$ events, and 33000 ${\pi }^{+}{\pi }^{-}$ events. The systematic and statistical errors of measuring the pion form factor are equal to 1.2-4.2 and 5-13%, respectively.
