GRK 683:  Hadrons in Vacuum, in Nuclei and Stars

• Subject Area: Condensed Matter Physics
• Term: from 2001 to 2009
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 273235

The international research training group Basel - Tuebingen is investigating at low energies the properties of elementary particles and their excited states with quantum chromodynamics and effective field theories, which approach quantum chromodynamics at low energies, in theoretical and experimental studies. Modifications of the properties of elementary particles in nuclear matter of different densities and temperatures, like in neutron stars and in the collision of two heavy nuclei are investigated. The structure of nuclei is studied in the valley of stability and for unstable nuclei with high proton and neutron numbers. These radioactive nuclei play an important role in the formation of the elements in the big bang, in nuclear reactions in stars, in nova and supernova explosions. Neutrinos carry for supernovae the largest part of the energy. To investigate the properties of neutrinos the neutrinoless double beta decay is studied. It allows to test "New physics" beyond the electroweak and the strong interaction.
