Description
The anomalous magnetic moment of the muon is sensitive to loop
contributions from all sectors of the Standard Model and, potentially,
to virtual particles of New Physics. In fact, since many years there
is an intriguing discrepancy of 3-4 standard deviations between
experiment and theory. However, the hadronic uncertainties from vacuum
polarization and light-by-light scattering dominate the theory error
and make it difficult to interpret this deviation as a clear sign of
New Physics. We present some recent developments in the theory of the
muon g-2 and give an update on the current status. We end with an
outlook on how to better control the hadronic uncertainties, in order
to fully profit from planned future muon g-2 experiments to test the
Standard Model and to constrain models of New Physics.
