Abstract:

The properties of strongly interacting matter at high temperature and/or density are very different from the properties of the nuclear matter our world is made of. Under such extreme conditions, a color-deconfined medium called the Quark-Gluon Plasma (QGP) prevails. The relevant degrees of freedom of the QGP no longer are the nucleons that constitute nuclear matter but instead quarks and gluons, which are the elementary building blocks of strongly interacting matter and the exchange bosons mediating the interaction between them, respectively. Ultra-relativistic collisions of gold and lead atomic nuclei at the Relativistic Heavy-Ion Collider at Brookhaven National Laboratory (USA) and at the Large Hadron Collider at CERN (Switzerland) offer the unique opportunity to produce such a form of strongly interacting matter and investigate its properties. In the future, corresponding experiments will be conducted also at lower energies at FAIR at GSI (Germany). An overview over the physics of heavy-ion collisions will be given and selected results will be discussed.
