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 

This includes:

    * Scattering experiments, pionic and kaonic atoms

    * Correlations 

     * 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 


Learning Outcome

Modern experiments at different accelerator facilities to study low energy QCD processes involving hadrons and their interaction with nuclear matter under different temperature and density conditions will be presented. A complete overview of the observables and the techniques to extract the latter from experiments with accelerated beam up to few GeV will be provided.

The focus will be on Hadron properties within nuclear matter and in particular we will learn how this can be connected to a possible observation of chiral symmetry restauration. Another rather hot topic in our field is the tests with terrestrial experiments of diferent hypotheses for the content of neutron stars. The state of the art of this kind of research will be discussed as well.
