9. Course learning outcomes

-Description of the learning outcomes provided to students by the course
- See the competence map (

The student will learn

  • principle of Higgs mechanism, and the reasons behind it, e.g. unitarity in the Standard Model
  • to apply Higgs mechanism in various models, including the Standard Model and minimal supersymmetric standard model
  • the consequences of Higgs mechanism (Higgs branching ratios, Higgs production)
  • effects of radiative corrections on Higgs physics
  • effective potential, its improvement
  • vacuum stability, fixed point and triviality
  • use of various Higgs representations, e.g. in grand unification


10. Course completion methods

-Will the course be offered in the form of contact teaching, or can it be taken as a distance
learning course?
-Description of attendance requirements (e.g., X% attendance during the entire course or
during parts of it)
-Methods of completion

  • Lectures are each weak, exercise session for the returned homework are once per weak. In the end of the term, there is a written home exam.
