Content, Learning Outcome and Preconditions
We will focus on the experimental test of the strong Interaction in the non-perturbative regime ( Low Energy QCD)
and explore the connections to astrophysics with examples from modern and contemporary experiments.
In the first semester, we will focus on the pillars of the strong interactions and treat:
* Chiral Symmetry Breaking (CSB) and possible Restauration (CSR)
CSB is linked to the origin of the hadron mass and experimentally very challenging to explore.
A historical review of the attempts and state of the art of the results will be discussed.
* Hadron properties in the nuclear medium and link to CSR
Hadron properties within nuclear matter at different densities are on one hand connected to the search of CSR but on the other end relevant for the description of objects such as neutron stars. The key experiments will be studied
* Meson-Nucleon and Meson-Nucleus Interaction
* Hyperon-Nucleon interaction
The behaviour of hadrons in matter depend on the two-body and three-body interactions. The experimental method
used to access them will be discussed
* Scattering experiments, pionic and kaonic atoms
* Hadronic Resonances and Exotic bound state in low energy QCD
* Link to dense and cold system as Neutron Stars
At the end of the course, the link to the physics of neutrons stars will be made and
then further expanded in the second module of the course during the sommer
After this course the student will get an overview about
1) Modern experiments at different accelerator facilities and the study of low energy QCD processes involving hadrons
2) Hadrons interaction with nuclear matter under different temperature and density conditions and link to the phase transitions
possible for nuclear matter
3) How are the properties of hadrons within dense and hot nuclear matter correlated to the observation of chiral symmetry restoration. An overview about the implications of chiral symmetry breaking
4) Experimental techniques and observables at accelarator experiments at different energies related to astrophysics
5) Why are hadrons with strange quarks relevant in the study of low energy QCD
6) Kaonic, pionic and hyper-nuclei
7) heavy ion collisions and their power
8) Dileptons and hadrons final states as probes of low energy QCD properties

Learning and Teaching Methods
The course will be based on scientific articles, mainly experimental works, that will be explained and discussed.
The articles treated during the course will be distributed during each lessons to the students.
Slides with all the exposed material will also be made available to the students.
Explenatory examples will be presented at the blackboard.

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 can be understand the origin of the hadron mass?
- Which is the experimental signature of chiral symmetry restoration?
- How can we measure the properties of the hadrons in hot and dense nuclear matter?
- How can we relate the hadron properties measured in hadron collisions at accelerators with astrophysics processes?
- What are pionic and kaonic atoms and how can one produce them?
- What are the properties of hyper nuclei?
- Why are dileptons the best experimental probes to study the hadrons properties within nuclear matter?
The exam may be repeated at the end of the semester.
