摘要:Some selected tests of the electroweak theory at an e+e− Linear Collider are
discussed. Improved measurements of fundamental parameters such as the e
ective weak
mixing angle, the W-boson mass, or the top-quark mass, allow to strengthen the precision
tests of the electroweak theory considerably. Moreover, an e+e− Linear Collider is an
ideal instrument to investigate the Higgs sector of the Standard Model or, more generally,
the mechanism of electroweak symmetry breaking. To this end, also the properties and
interactions of the top quark can be studied accurately. An e+e− Linear Collider is
also a well-suited tool to study physics beyond the Standard Model. Thus, for instance,
the spectrum of supersymmetric theories can be explored with high precision, and the
underlying fundamental theory can be reconstructed. In order to achieve all these goals,
a lot of theoretical precision calculations are necessary.
