| dc.description | The problem of estimating the 10th order QED corrections to the muon anomalous magnetic moment is reconsidered. The incorporation of the recently improved contributions to the $α^4$ and $α^5$- corrections to $a_μ$ within the renormalization-group inspired scheme-invariant approach leads to the estimate $a_μ^{(10)}\approx 643(α/pi)^5$. It is in good agreement with the estimate $a_μ^{(10)}= 663(20) (α/π)^5$, obtained by Kinoshita and Nio from the numerical calculations of 2958 10-th order diagrams, which are considered to be more important than the still uncalculated 6122 10th-order $m_μ/m_e$-dependent vertex graphs, and 12672 5-loop diagrams, responsible for the mass-independent constant contribution both to $a_μ$ and $a_e$. This confirms Kinoshita and Nio guess about dominance of the 10-th order diagrams calculated by them. Comparisons with other estimates of the $α^5$- contributions to $a_μ$, which exist in the literature, are presented. | |
