Abstract:
Searches for extensions of the standard model of particle physics
will play an important role in future experiments at the LHC
(so-called High Energy Frontier). In this talk we will discuss a
complementary approach to look for New Physics, in which experiments
are performed at low or intermdiate energies with extremely high precision
(so-called Precision Frontier). The anomalous magnetic moment of
the muon is a very sensitive variable for these kind of
precision tests.
We will discuss in this talk the hadronic corrections to (g-2) of the muon, which are the limiting factors for the standard model prediction of the muon anomaly and which require precision measurements of the hadronic cross section in electron-positron annihilation. The status of those measurements and a future outlook will be given.
