Hadronic Loop Corrections to the Muon Anomalous Magnetic Moment
Abstract
The dominant theoretical uncertainties in both, the anomalous magnetic moment of the muon and the value of the electromagnetic coupling at the Z scale, M_Z, arise from their hadronic contributions. Since in the future these will also dominate the experimental errors, we study the correlation between them, as well as with other fundamental parameters, such as the strong coupling constant. We present analytical formulas for the QCD contribution from higher energies and from heavy quarks, and discuss how to efficiently correlate the remaining uncertainties in a simultaneous analysis.Keywords
