摘要

This chapter provides a theoretical overview of the muon anomalous magnetic moment \(a_\mu \) , including its QED, electroweak, hadronic vacuum polarization (HVP), and hadronic light-by-light (HLbL) contributions. It further introduces the radiative return method for measuring \(e^+e^- \rightarrow hadrons\) cross sections and outlines the measurement strategy adopted in this thesis for the \(e^+e^- \rightarrow \pi ^+\pi ^-\pi ^0\) channel.
