Forschungsförderungsprojekt
Quantenchromodynamics, the fundamental theory of the nuclear forces in terms of never directly observed quarks and gluons, has been studied at extreme temperatures and densities by means of collider experiments using heavy ions. These experiments have produced evidence for a new form of matter, the quark-gluon plasma, with surprisingly strong collective behavior that cannot be accounted for by conventional methods. Methods deriving from superstring theory, using a holographic description of gauge theories at high temperatures by means of 5-dimensional geometries with imbedded black holes, have been successfully applied for modelling a strongly coupled quark-gluon plasma. With the new accelerator LHC at CERN, heavy-ion collision experiments will soon probe substantially higher energies where the transition to an essentially weakly coupled quark-gluon plasma might be observed. The latter holds the promise of new collective effects such as non-Abelian plasma instabilities. The aim of this project will be to study equilibrium and non-equilibrium features of the quark-gluon plasma for both strongly and weakly coupled quark-gluon plasmas and their respective characteristics.
