本文报告了规范不变集（称为集 III(c)）对轻子的十阶 QED 贡献，该集由 390 个费曼顶点图组成，其中包含内部四阶逐光散射子图。组 III(c) 对电子 () 的质量无关贡献为 4.9210 (103)，单位为 。包含 μ 子环的图的质量相关贡献为 0.00370 (37)。目前，tau-轻子环的贡献可以忽略不计。 Set III(c) 的总贡献为 4.9247 (104)。我们还评估了闭合电子环对 muon() 的贡献。结果是 7.435 (134)。 tau-轻子环的贡献为 0.1999 (28)。 III(c)组的各种轻子环（电子、μ子和τ轻子）的总贡献为12.556（135）。
This paper reports the tenth-order QED contribution to the leptonfrom the gauge-invariant set, called Set III(c), which consists of 390 Feynman vertex diagrams containing an internal fourth-order light-by-light-scattering subdiagram. The mass-independent contribution of Set III(c) to the electron() is 4.9210 (103) in units of. The mass-dependent contributions tofrom diagrams containing a muon loop is 0.00370 (37). The tau-lepton loop contribution is negligible at present. Altogether the contribution of Set III(c) tois 4.9247 (104). We have also evaluated the contribution of the closed electron loop to the muon(). The result is 7.435 (134). The contribution of the tau-lepton loop tois 0.1999 (28). The total contribution of various leptonic loops (electron, muon, and tau-lepton) of Set III(c) tois 12.556 (135).
