The measurement is based on a full dataset collected below 1 GeV during three data taking seasons, corresponding to an integrated luminosity of about 62 pb$^{-1}$. In the dominant $蟻$-resonance region, a systematic uncertainty of 0.7% has been reached. At energies around $蠁$-resonance the $蟺^+蟺^-$ production cross section was measured for the first time with high beam energy resolution. The forward-backward charge asymmetry in the $蟺^+蟺^-$ production has also been measured. It shows a strong deviation from the theoretical prediction based on the conventional scalar quantum electrodynamics framework, and it is in good agreement with the generalized vector-meson-dominance and dispersive-based predictions. The impact of the presented results on the evaluation of the hadronic contribution to the anomalous magnetic moment of muon is discussed. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2302.08834v3-abstract-full').style.display = 'none'; document.getElementById('2302.08834v3-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 5 June, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 17 February, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">54 pages, 36 figures; as published in Phys.

The decay mode $畏\rightarrow纬纬$ is used for $畏$ meson reconstruction in the data sample corresponding to an integrated luminosity of $78.3$ pb$^{-1}$. The energy dependence of the $e^{+}e^{-}\rightarrow畏蟺^{+}蟺^{-}$ cross section is fitted within the framework of vector meson dominance in order to extract the $螕(蟻(1450)\rightarrow{^{+}e^{-}})\mathcal{B}(蟻(1450)\rightarrow畏蟺^{+}蟺^{-})$ and the $螕(蟻(1700)\rightarrow{e^{+}e^{-}})\mathcal{B}(蟻(1700)\rightarrow畏蟺^{+}蟺^{-})$ products. Based on conservation of vector current, the analysed data are used to test the relationship between the $e^{+}e^{-}\rightarrow畏蟺^{+}蟺^{-}$ cross section and the spectral function in $蟿^-\rightarrow畏蟺^-蟺^0谓_蟿$ decay. The $e^{+}e^{-}\rightarrow畏蟺^{+}蟺^{-}$ cross section measured with the CMD-$3$ detector is in good agreement with the previous measurements. <a class="is-size-7" style="white-space: nowrap;"
