"The equation of state and deconfinement in QCD"

Abstract:

The low-energy phase of the theory of strong interactions, Quantum
Chromodynamics (QCD), features a remarkable property of confinement -
the spectrum contains composite, color-neutral states, while states
with non-zero color charge are not observed. At high temperatures
and/or densities the strongly interacting matter undergoes a
transition into the deconfined phase called Quark-Gluon Plasma
(QGP). The properties of QGP are being studied experimentally at the
Relativistic Heavy-Ion Collider (RHIC) at BNL and the Large Hadron
Collider (LHC) at CERN. On the energy scales accessible to the
experiments the theory is still strongly coupled and lattice gauge
theory provides a non-perturbative approach for solving it with
stochastic methods. I review recent progress in understanding the
thermodynamics of QCD: properties of the transition into the
deconfined phase, signatures of deconfinement and restoration of the
chiral symmetry, and the equation of state of QGP at high temperature
and density.
