Hadronic loop corrections to the muon anomalous magnetic moment - art. no.071804

The dominant theoretical uncertainties in both the anomalous magnetic momen t of the muon and the value of the electromagnetic coupling at the Z scale, M-z, arise from their hadronic contributions. Since these will ultimately dominate the experimental errors, we study the correlation between them, as well as with other fundamental parameters. To this end we present analytic al formulas for the QCD contribution from higher energies and from heavy qu arks. Including these correlations affects the Higgs bosun mass extracted f rom precision data.
