摘要：

This paper reports the tenth-order QED contribution to lepton g - 2 from diagrams of three gauge-invariant sets VI(d), VI(g), and VI(h), which are obtained by including various fourth-order radiative corrections to the sixth-order g - 2 containing light-by-light-scattering subdiagrams. In the case of electron g - 2, they consist of 492, 480, and 630 vertex Feynman diagrams, respectively. The results of numerical integration, including mass-dependent terms containing muon loops, are 1: 8480 (69) (alpha/pi)(5) for the Set VI(d), -1: 5909 (62) (alpha/pi)(5) for the Set VI(g), and 0.1793 (39) (alpha/pi)(5) for the Set VI(h), respectively. We also report the contributions to the muon g - 2, which derive from diagrams containing an electron, muon or tau-lepton loop: Their sums are -5.990 (591) (alpha/pi)(5) for the Set VI(d), 5: 323 (472) (alpha/pi)(5) for the Set VI(g), and -8.362 (alpha/pi)(5) for the Set VI(h), respectively.
