Analytical expressions for the tenth order electromagnetic corrections to the lepton ($L=e, ~\mu $ and $\tau$) anomaly $a_L$ are derived explicitly for a class of Feynman diagrams with insertions of the vacuum polarization operator consisting of four

We investigate the radiative QED corrections to the lepton ($L=e,~\mu$ and $\tau$) anomalous magnetic moment arising from vacuum polarization diagrams by four closed lepton loops. The method is based on the consecutive application of dispersion relat

We investigate the radiative quantum electrodynamic (QED) corrections to the lepton ($L=e, ~\mu $ and $\tau$) anomalous magnetic moment due to the contributions of diagrams with insertions of the photon vacuum polarisation operator consisting solely

The contributions to the anomalous magnetic moment of the lepton $L$ ($L=e\ , \mu $ or $\tau$) generated by a specific class of QED diagrams are evaluated analytically up to the eighth order of the electromagnetic coupling constant. The considered cl

A new approximation is proposed for the contour of the stationary phase of the Mellin--Barnes integrals in the case of its finite asymptotic behavior as ${\rm Re} z\to -\infty$. The efficiency of application of the proposed contour and the quadratic

We apply the Mellin transformation method to the recovery form of the fragmentation function using two efficient approximations for the contour of the stationary phase. The first contour is of parabolic form and runs from the saddle point. A new app

We apply the Mellin transformation method to estimate Q 2 -dependence of the F3 structure function using the efficient contour running from a saddle point proposed by Kosower. Considering a contour of the stationary phase, we examine how to improve t

We estimate the accuracy of the reconstruction of the structure function xFs (x, Q ) by the Mellin inverse transformation method using the parabolic contour running from a saddle point proposed by Kosower. The choice of the contour is of great prac
