Theory of Lepton g-2: Improvement of QED Terms.
T.Kinoshita
Abstract:
All
469 $\alpha^4$ terms which depend on the electron-muon mass ratio
have been evaluated in two or more independent
formulations. Evaluation of many
$\alpha^5$ terms are in progress. Uncertainties in
both $\alpha^4$ and $\alpha^5$
terms have been reduced substantially, eliminating
QED as a possible source of
theoretical uncertainty in the muon g-2.
