Learning Outcome

After successful completion of the module the students are able to:

  • understand approches of the dependence on processes of the strong interaction of the relevant energy scale of the scattering
  • understand experimental methods based on the application of QCD
  • apply methods for the classification of hadronic end states (jet and Eventshape Algorithms)
  • understand methods for determining the coupling constant in QCD
  • understand Applications of the models for fragmentation of jets


No preconditions in addition to the requirements for the Master’s program in Physics.

Learning and Teaching Methods

The module consists of a lecture and exercises.

In the first lectures the basic experimental foundations of the theory of strong interactions are discussed. In this way the students understand, that the theory is well supported experimentally. Through detailed work with these topics we also achieve that the experimental methods for proving a theoretical assumption in particle physics become transparent. The students are encouraged to ask and answer questions, so that the essential topics will be well understood. In the progress of the lectures we will cover modern measurements of particle physics and interpret them with the help of the foundations learned here. In this way the students learn to place recent measurements of particle physics in the context of strong interaction physics.

The problems and excercise hours, which are a place to discuss the problems in detail, deepen the understanding. In particular the problems are given in such a way that they cover important aspects of the lectures and go through details of proofs for which there would otherwise not be enough room in the lectures. In this way the students learn to use and apply the material learned in the lectures.


Lectures as presentations, printed script of the lectures, problem sheets.


A detailed list of literature will be distrbuted with the script of the first lecture.

Module Exam

Description of exams and course work

There will be a written exam of 60 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.

In accordance with §12 (8) APSO the exam can be done as an oral exam. In this case the time duration is 25 minutes.

For example an assignment in the exam might be:

  • Show that the observable thrust in e+e- events approches the value 1/2 for spherical events.
  • Derivation and approximations of angular ordering in the parton shower

In the exam the following learning aids are permitted: Scipt of the lectures

Participation in the tutorials is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.
