Update of g-2 of the muon and Delta alpha

Published 29 Jan 2010 in hep-ph | (1001.5401v1)

Abstract: We update our Standard Model predictions for g-2 of the muon and for the hadronic contributions to the running of the QED coupling, Delta alpha^{5_had(M_Z^2).} Particular emphasis is put on recent changes in the hadronic contributions from new data in the 2pi channel and from the energy region just below 2 GeV.
