Currently we use an effective field theory approach to investigate electro-weak processes on nucleons and light nuclei. This effective theory reflects the fundamental symmetries of Quantum Chromo-Dynamics ---- the theory of the strong interaction among the quarks. The quarks are the basic building blocks of hadrons. Guided by the chiral symmetry requirements of strong interaction, we are investigating when and how effective meson degrees of freedom of the nucleus (exchange currents) can be observed.
During a supernova explosion nuclear matter is compressed to high densities (tightly packed protons and neutrons). From reasonable theoretical extrapolations it is suspected that a strange meson condensate can form at these high nuclear densities. We are examining the dynamics leading to a possible formation of a meson condensate. Since nucleons consist of confined quarks, another question of importance at high nuclear densities is how and under what conditions these quark degrees of freedom affect nuclear observables.
Antimatter interactions with matter is a violent process. The annihilation of matter and antimatter converts mass to energy and is closely connected to the quark and antiquark structure of the nucleon and antinucleon. Once laboratories in Germany (GSI) and Japan (JPARC) have intense anti-proton beams, we will consider a renewed investigation of the annihilation process making use of phenomenological quark models.
