The improved 10th order QED expression for a_{\mu} : new results and related estimates

Abstract

New estimates of the 10th order QED corrections to the muon anomalous magnetic moment are presented. The estimates include the information on definite improved 10th order QED contributions to $a_{\mu }$, calculated by Kinoshita and Nio. The final estimates are in good agreement with the ones, given recently by Kinoshita.
