Title: High Density QCD with heavy-ion and proton beams
Speaker: Dr. Jan Fiete Grosse-Oetringhaus (CERN)
Abstract:
It is more than 35 years ago that the first heavy-ion collisions occurred at CERN and in the meanwhile an exploratory field has reached the precision era. A deconfined state of matter, the Quark-Gluon Plasma, is produced in sufficiently relativistic heavy-ion collisions which has today been characterized in great detail. A particular important experimental tool is the search for collectivity and the close-to-perfect fluidity of the Quark-Gluon Plasma has been demonstrated. Surprisingly, signatures of collectivity have been identified within the last decade also in collision systems as small as pp and p-Pb, where such phenomena had been assumed to be absent traditionally. Precursor phenomena may have been found even in ep and ee collisions.
The seminar will give a review of studies of the high-density regime of the QCD phase diagram with heavy-ion and proton beams. The nature of the Quark-Gluon Plasma, the onset of its production as well as the transition to hadrons will be discussed. A set of observables will be introduced which allow one to understand the key properties of the Quark-Gluon Plasma. The state-of-the-art of studies in small collision systems will be presented and put in context to our understanding of the Quark-Gluon Plasma and its onset.
