中文摘要
用微扰理论计算了QED对电子和Muon反常磁矩的贡献。我们能够迅速得到结果,因为我们自动化了程序编码,并进行了大规模的数值计算来评估结果。然后恢复了对电子反常的八阶贡献。利用新的理论公式,精确地确定了电磁力的基本常数--精细结构常数。此外,我们还确定了十阶微扰的贡献,尽管这是初步的。
英文摘要
The QED contributions to the anomalous magnetic moments of the electron and muon have been calculated by using perturbation theory. We were able to obtain the results promptly, because we automated program cording and performed large-scale numerical calculation to evaluate the resultant programs. Then the eighth-order contribution to the electron anomaly was renewed. By using the new theory formula, the fine-structure constant, which is a fundamental constant of electro-magnetic force, was precisely determined. Furthermore, we determined the contribution from the tenth-order perturbation, although it is preliminary.
