在BaBar的低能强子截面测量和μ子g-2的意义

Low-energy hadronic cross sections measurements at BaBar, and implication for the g-2 of the muon

Denis Bernard, The BaBar Collaboration

摘要:

BaBar合作组织有一个密集的项目,研究低能e+e湮灭中强子产生的截面,可通过初始态辐射获得。我们的测量允许μ子异常磁矩的预测值的精度显着提高。这些改进对于揭示预测值和实验值之间当前> 3 sigma的差异是必要的。我们已经发表了一些在终态中有2到6个强子的过程的结果,其他终态目前正在调查中。我们在这里报告通过分析整个Babar数据集获得的最新结果。

英文摘要:

The BaBar Collaboration has an intensive program studying the cross sections of hadron production in low-energy e+e- annihilation, accessible via initial-state radiation. Our measurements allow a significant improvement in the precision of the predicted value of the muon anomalous magnetic moment. These improvements are necessary for shedding light on the current > 3 sigma difference between the predicted and the experimental values. We have published results on a number of processes with two to six hadrons in the final state, and other final states are currently under investigation. We report here on the most recent results obtained by analysing the entire Babar dataset.
