Recent Results from the CMD-3 Detector at the VEPP-2000 e+e– Collider
We report about measurement of the $${{e}^{ + }}{{e}^{ - }} \to {{\pi }^{ + }}{{\pi }^{ - }}$$ process cross section performed with the CMD-3 detector at VEPP-2000 $${{e}^{ + }}{{e}^{ - }}$$ collider. Integrated luminosity for the measurement is about 88 pb–1 collected in center-of-mass energy range from 0.32 to 1.2 GeV. Systematic error of the cross section near $$\rho $$ (770) resonance is about 0.7%. The cross section values are used for evalution of the hadronic contribution to $${{(g - 2)} \mathord{\left/ {\vphantom {{(g - 2)} 2}} \right. \kern-0em} 2}$$ of muon.
