Physical Review Letters, 2024•APSThe cross section of the process e+ e-→ π+ π-has been measured in the center-of-mass
energy range from 0.32 to 1.2 GeV with the CMD-3 detector at the electron-positron collider
VEPP-2000. The measurement is based on an integrated luminosity of about 88 pb-1, of
which 62 pb-1 represent a complete dataset collected by CMD-3 at center-of-mass energies
below 1 GeV. In the dominant region near the ρ resonance a systematic uncertainty of 0.7%

The cross section of the process has been measured in the center-of-mass energy range from 0.32 to 1.2 GeV with the CMD-3 detector at the electron-positron collider VEPP-2000. The measurement is based on an integrated luminosity of about , of which represent a complete dataset collected by CMD-3 at center-of-mass energies below 1 GeV. In the dominant region near the resonance a systematic uncertainty of 0.7% was achieved. The implications of the presented results for the evaluation of the hadronic contribution to the anomalous magnetic moment of the muon are discussed.
