Content, Learning Outcome and Preconditions
This lecture introduces supersymmetric theories in four and more dimensions. The basis of this course lies in the understanding of the supersymmetry algebra and its representations with N=1 or more supersymmetry generators. The following topics are covered:
- mathematical foundation: Grassmann variables
- supersymmetry algebra and its representations: chirale superfields, vector superfields
- superfields and superspace as an extension of fields and space
- supersymmetric theories in four dimensions: superpotential and Kähler potential
- non-renormalization theorems
- overview on supergravity, introduction of supergravity as local supersymmetry
- supersymmetry-breaking using F- und D-terms
- the MSSM: particle spectrum, symmetries and interactions
- extra dimensions and Kaluza-Klein compactification
- spinors and supersymmetry in extra dimensions
After successful completion of the module the students are able to:
- understand recent literaure on supersymmetric theories.
- follow talks on supersymmetric extensions of the Standard Model.
- learn extended theories, like "Grand Unified Theories" in extra dimensions and string theory.
No preconditions in addition to the requirements for the Master’s program in Physics.
Courses, Learning and Teaching Methods and Literature
Learning and Teaching Methods
The mathematical and theoretical foundations are introduced carefully and well motivated. Several examples and explicit calculations are used to deepen the insight and to illustrate the content. The main concepts are repeated at the beginning of each lecture and discussed with the students. Thus the students are able to explain and apply the learned physics knowledge independently.

- repetitions at the beginning of each lecture using beamer-presentations

Description of exams and course work
There will be an oral exam of 25 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and sample calculations.
For example an assignment in the exam might be:
- How does a chiral superfield transform under a supersymmetry transformation?
- How does one write down a supersymmetric Lagrangian?
- How does the scalar potential look like when supersymmetry is broken spontaneously?
In the exam no learning aids are permitted.
