The theoretical estimate of the anomalous magnetic moment of the muon is lower than the experimental measurement by approximately 3 standard deviations. The precision of the Standard Model (SM) prediction is limited by hadronic contributions, of which the Leading Order Vacuum Polarisation (LOVP) contribution has the largest uncertainty. By carefully processing new electron-positron-to-hadron experimental cross section data, we aim to improve the accuracy and precision of the hadronic contribution to the muon g-2 to help to clarify the origin of the discrepancy between theory and experiment.

μ子反常磁矩的理论估计值比实验测量值低约3个标准偏差。标准模型（SM）预测的精度受到强子贡献的限制，其中首阶真空极化（LOVP）的贡献具有最大的不确定性。通过对新的电子-正电子-强子截面实验数据的仔细处理，我们的目标是提高强子对μ g-2的贡献的准确性和精确度，以帮助澄清理论与实验之间差异的根源。
