Gruppi di ricerca AA - Fundamental Physics of Nuclei and Nucleons
Descrizione This programme focuses on the study of nuclear matter under extreme conditions of high temperature and high density. In this limit, the important degrees of freedom are thought to be quarks and gluons, rather than hadrons. This state of matter, known as a quark-gluon plasma (or QGP), is described by Quantum Chromodynamics. It is therefore expected that when nuclear matter is compressed and heated in a high energy collision, a phase transition may occur. The transition marks the change of state from quark confined hadronic matter, to a plasma phase, where quarks and gluons have become liberated over a volume comparable with that of the colliding nuclei. This novel state of matter must have existed during the first fraction of a second after the Big Bang and may exist today in the core of dense stellar objects such as neutron stars.
