Contributions of QED Diagrams with Polarization Insertions to the Lepton Anomaly within the Mellin-Barnes Sepresentation / O.Solovtsova, V.Lashkevich, L.P.Kaptari // Физика элементарных частиц и атомного ядра. – 2024. – Т. 55, № 4. – P. 852. – URL: http://www1.jinr.ru/Pepan/v-55-4/07_Solovtsova_ann.pdf.
We investigate the radiative QED corrections to the lepton (L = e, μ and τ ) anomalous magnetic moment arising from vacuum polarization diagrams by four closed lepton loops. The method is based on the consecutive application of dispersion relations for the polarization operator and the Mellin–Barnes transform for the propagators of massive particles. This allows one to obtain, for the first time, exact analytical expressions for the radiative corrections to the anomalous magnetic moments of leptons from diagrams with insertions of four identical lepton loops, all of the same type different from the external one, L. The result is expressed in terms of the mass ratio r = m/mL. We investigate the behaviour of the exact analytical expressions at r → 0 and r → ∞ and compare with the corresponding asymptotic expansions known in the literature.
