The Hadronic Vacuum Polarisation Contribution to the Anomalous Magnetic Moment of the Muon

介子反常磁矩的理论估计值比实验测量值低约3个标准差。标准模型(SM)的预测精度受到强子贡献的限制，其中前序真空极化(LOVP)贡献的不确定性最大。通过仔细处理新的电子-正电子-强子实验截面数据，我们的目标是提高强子对Muon g-2贡献的准确性和精确度，以帮助澄清理论和实验之间差异的根源。

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.
