Precise measurements of the hadronic cross sections with the CMD-3 and SND detectors at the VEPP-2000 e + e - Collider
It's good known the difference in 3.5 sigma between the muon (g - 2) experimental result and its calculation in Standard Model. To clarify this intriguing discrepancy the new stage of muon (g - 2) measurement is under preparation at Fermi National Laboratory. On other hand, regular data taking for measurements of hadron cross section production in e+ e- annihilations is under way since December 2010 at the electron-positron collider VEPP-2000 with the CMD-3 and SND detectors. The collected data sample corresponds to about 60 inverse picobarns of integrated luminosity per detector in the energy range from 0.32 up to 2 GeV. Preliminary analysis of various hadronic cross sections has been performed. © Owned by the authors, published by EDP Sciences, 2014.
