Abstract:
The anomalous magnetic moment (g-2) of the muon is an extremely
precisely measured and calculated low-energy observable. At the current
level of precision it is sensitive to all known elementary particle
interactions, and even to potential new physics at the TeV scale or
below. The talk will first give a brief review of the current status of
the experiment and Standard Model calculations. According to most recent
results, there is a discrepancy of around 4 standard deviations, which
might be due to new physics. In the second part of the talk the impact
of this result on new physics models is explained. Supersymmetry as a
particularly promising scenario is disussed in detail, but also
alternatives are mentioned. An outlook on future experimental progress
is given.
