Hadronic Contribution

The dominant contribution to the uncertainty of the theoretical prediction of the (g-2) of the muon comes from the leading order hadronic vacuum polarization part. This contribution is evaluated using either tau or e+e-experimental data. The same experimental data are exploited for QCD studies. We present an update of the ALEPH hadronic spectral functions. This update induces only small changes for the hadronic contribution to the (g-2) of the muon and for the QCD fits. We also present updates of the contributions to g-2 for several channels of e+e-into hadrons.
