Characterizing the QCD Plasma — •Andrea Dubla — GSI Helmholtz Center for Heavy Ion Research

Under extreme conditions of high temperature and density, QCD predicts the formation of a new state of matter, the so-called quark-gluon plasma (QGP), in which quarks and gluons are the relevant degrees of freedom. Our universe is thought to have been in such a primordial state for the first few millionths of a second after the Big Bang, before quarks and gluons were bound together to form protons and neutrons. Heavy-ion collisions at ultra-relativistic energies at the Large Hadron Collider at CERN produce the unique conditions to form the QGP in the laboratory. Recreating this primordial state of matter and understanding how it evolves will allow us to shed light on questions about how matter is organized and the mechanisms that confine quarks and gluons. This talk gives an overview of the experimental program, based on selected recent results and comparison with model calculation, that allowed after decades to characterize with unprecedented precision this form of strongly interacting matter and its dynamic.
