Annotation

In the summer semester we shall initially focus on supersymmetry as another widely popular area of the BSM physics, discuss its basic structure, model building strategies as well as its basic phenomenological aspects.

Then we shall inspect in some detail the minimal potentially realistic supersymmetric extension of the Standard

Model, the Minimal Supersymmetric Standard Model, MSSM.
