Precise study of the hadrons production in $e^+e^-$ annihilation at low energies provides important information about interactions of light quarks and spectroscopy of their bound states. These studies are especially important for theoretical calculations of the muon $(g-2)$ via the Standard Model because of the present difference between theoretical and experimental values exceeds three standard deviations. In this report we will discuss current status and recent results obtained by the CMD-3 experiment and will give a brief look to status of the BaBar and Belle II experiments.

Author comments upon resubmission

Dear Prof.Onderwater, dear colleagues,

Thank you very much for careful reading and corrections.
The corrected versions is attached. Best regards, Sorry, but my contribution
is not uploaded to arXiv.


List of changes

Usage of articles can be improved somewhat:
"... it is clear that THE low energy range provides THE dominant contribution to this value."


"Until 2010 *the* precise data on the hadronic cross sections obtained in the energy scan
mode were provided by experiments at THE VEPP-2M collider " -> scrap first 'the'


"THE new VEPP-2000 e+e− collider for the center-of-mass energy range from 0.3 to 2 GeV
has been operating at BINP"


"A special system based on the Compton back scattering ..."


"Then experiments at VEPP-2000 were resumed in 2017 after A three year shutdown taken for THE new intensive positron injection source implementation as well as for AN upgrade of THE 1 GeV booster."


"... a compact multipurpose detector COMBINING magnetic spectrometry with high resolution calorimetry"
"THE main instrument of the SND detector, ... , is A high resolution calorimeter ..."
"THE dominant contribution to the ahμ value ..."


"... cross section is AN important part of the experiments ..."


Fig. 3: slight cut-off on the top-left

figure corrected

"However, other channels, for example 2(π+π−), DO not demonstrate ..."


sublect -> subject


Caption fig. 7: "... process measured by *the* CMD-3" -> remove 'the' (same in caption fig. 8 for *the* SND).
Also caption fig. 7: "THE vertical lineS indicate the pp ̄and nn ̄ thresholds ..." Note: 'and' inside math-mode.


"The VEPP-2000 resumed operation in 2017 after A three year shutdown taken for new intensive positron injection source implementation as well as to upgrade THE 1 GeV booster."
