Description
Using new experimental data, the contribution to the anomalous magnetic moment of the muon from the π0γ and ηγ intermediate states in the vacuum polarization is calculated with high precision taking into account the correction for using the trapezoidal rule: αμ(π0γ) + αμ(ηγ) = (53.1 ± 1.5) x 10-11. It is found the small contribution from e+e-π0, e+e-η and μ+μ-π0 intermediate states equal to 0.5 x 10-11
Abstract (Russian)
С использованием новых экспериментальных данных вычислен вклад в аномальный магнитный момент мюона из π0γ и ηγ промежуточных состояний в вакуумной поляризации с высокой точностью, принимая во внимание поправку для использования трапецеидального правила αμ(π0γ) + αμ(ηγ) = (53.1 ± 1.5) x 10-11. Также найден вклад от e+e-π0, e+e-η и μ+μ-π0 промежуточных состояний, равный 0.5 х 10-11Additional details
