Title: Testing the SM at highest precision: g-2 of the muon and alpha_QED(M_Z)
Speaker: Dr Thomas Teubner (Liverpool)
The anomalous magnetic moment of the muon is discussed, paying particular attention to the evaluation of the hadronic contributions. Confronted with the latest measurement from BNL, the Standard Model prediction currently shows a 2.7 sigma deviation, allowing -- but at the same time constraining -- new physics. I also present a new result for alpha_QED(M_Z) which influences the indirect determination of the Higgs mass from fits of electroweak precision observables.
