Description
We report a measurement of the $e^+e^-\to\pi^+\pi^-\pi^0$ cross section in the energy range from 0.62$~$GeV to 3.5$~$GeV using an initial-state radiation technique. We use an $e^+e^-$ data sample corresponding to $191~\mathrm{fb}^{-1}$ of integrated luminosity, collected at a centre-of-mass energy at or near the $\Upsilon(4S)$ resonance with the Belle$~$II detector at the SuperKEKB collider. The uncertainty at the $\omega$ and $\phi$ resonances is 2.2%. The leading order hadronic vacuum polarization contribution to the muon anomalous magnetic moment using this result is $a^{3\pi}_{\mu}= (49.02\pm 0.23\pm 1.07)\times 10^{-10}$.
