Learning and Teaching Methods
The modul consists of a lecture and exercise classes.
The lecture is designed for the presentation of the subject, usuallyby blackboard presentation. The focus resides on theoretical foundations of the field, presentation of methods and simple, illustrative examples. Command of basic methods is deepened and practised through homework problems, which cover important aspects of the field. The homework problems should develop the analytic skills of the students and their ability to perform calculations. The homework problems are discussed in the ecercise classes by the students themselves under the supervision of a supervizor in order to develop the skills to solve and explain a physics problem coherently.
Blackboard presentation, additional Powerpoint slides/presentations on demand.

Description of exams and course work
There will be a written exam of 180 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.
For example an assignment in the exam might be:
- Calculate the propagator and the interaction vertices for a non-abelian gauge theory in a particular gauge fixing.
- Calculate the 1-loop corrections to a non-abelian gauge theory, regularize and renormalize.
- Extract the beta-function coefficients from the above calculation.
- Find the symmetry breaking pattern for a theory with spontaneous symmetry breaking, calculate the Goldstone boson interactions, find potentially anomalous symmetries.
- Derive the self-interactions of a spin 2 field using the decoupling of the Stueckelberg modes
Participation in the tutorials is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.
There will be a bonus (one intermediate stepping of "0,3" to the better grade) on passed module exams (4,3 is not upgraded to 4,0). The bonus is applicable to the exam period directly following the lecture period (not to the exam repetition) and subject to the condition that the student passes the mid-term of
- preparing at least 50 % of the exercises on the exercise sheets and
- presenting at least three exercises at the blackboard
The exam may be repeated at the end of the semester.
