PRECISION TESTS OF THE ELECTROWEAK THEORY

In this review we give a discussion of the structure of the standard m odel and its quantum corrections for testing the electroweak theory at present and future colliders. After a short summary of the tree level structure of the standard model we outline the calculation of physica l quantities at the quantum level. Concrete applications are given to the vector boson mass interdependence and the Z resonance. Finally we show a comparision of the standard model prediction for the electrowea k precision observables with the most recent experimental data.
