Abstract
As you will hear this afternoon, there has been remarkable progress in the measurement of lepton magnetic moments in the last few years. I should like to discuss what can be learned about the fundamental forces of nature from these and forthcoming developments.

These experiments can also be used to test other theoretical predictions, e.g. the CPT Theorem. From (3) and (4) we obtain (gμ—gμ+)/gμ = 2.6 (1.7) ×10−8 which provides the most accurate test of the CPT Theorem applied to muons. To achieve similar accuracy for electrons, the result (2) for must be improved substantially. Note, however, that the work of S. I. Serednyakov et al. (Phys. Lett. 66B, 102 (1977) has established the equality of ae− and ae− to a very high accuracy: ∣ae—ae+∣/ae ≤ 1.0×10−5. This is equivalent to ∣ge− − ge+∣/ge ≤ 1.2×10−8
All 72 diagrams have been evaluated by numerical integration, most of them by several groups. The most extensive work has been done by M. J. Levine and J. Wright (Phys. Rev. D8, 3171 (1973)), R. Carroll (Phys. Rev. D12, 2344 (1975), P. Cvitanovic and T. Kinoshita (ref. 8), and T. Kinoshita and B. Lindquist (ref. 9 ).
