Descripción
The strong interaction of quarks and gluons is at the origin of almost all of the mass of the visible universe. The underlying quantum field theory, Quantum Chromodynamics (QCD), is a consistent part of the highly successful Standard Model of elementary particles. The emergence of phases and structures in QCD, from quarks and gluons to mesons and baryons, to atomic nuclei and neutron stars, is one of the persistently fundamental issues in modern science. This colloquium reviews our current understanding of the phases of QCD. Empirical information from nuclear collisions at the highest available energies will be surveyed together with results of Lattice QCD thermodynamics. Important constraints on the phase diagram come from nuclear physics and the treatment of the nuclear many-body problem using modern effective field theory approaches based on the symmetry breaking pattern of low-energy QCD. The presentation concludes with a discussion of new conditions for the equation-of-state of dense baryonic matter derived from the recent observation of massive (two-solar-mass) neutron stars.
