# The phase diagram of QCD

@article{Hands2001ThePD, title={The phase diagram of QCD}, author={Simon J. Hands}, journal={Contemporary Physics}, year={2001}, volume={42}, pages={209 - 225} }

Simple thermodynamic reasoning is used to argue that at temperatures of the order of a trillion kelvin, QCD, the theory which describes strongly interacting particles such as protons and neutrons under normal conditions, undergoes a phase transition to a plasma of more elementary constituents called quarks and gluons. A review is presented of what is known about the plasma phase both from theoretical calculations and from experiments involving the collisions of large atomic nuclei moving at…

QCD as a theory of extended, strongly interacting matter is familiar from big bang evolution which, within the time interval from electro-weak decoupling (10−12 s) to hadron formation (5 × 10−6 s),…

The QCD Phase Diagram

- Physics
- 2012

In this chapter, we turn to the phase structure of strongly interacting matter as a function of finite baryon density. We first discuss the different limiting forms for mesonic and baryonic matter,…

This review will be concerned with our knowledge of extended matter under the governance of strong interaction, in short: QCD matter. Strictly speaking, the hadrons are representing the first layer…

Valon-hadron crossover and phenomenology of quark-gluon plasma in the context of lattice calculations

- Physics
- 2007

The phase crossover in the energy range ΔT ≃ 50–60 MeV as explicitly suggested by the results of lattice calculations at μ = 0 is interpreted here in terms of an evolving superposition of hadron and…

A steep maximum occurs in the Wroblewski ratio between strange and non‐strange quarks created in central nucleus‐nucleus collisions, of about A=200, at the lower SPS energy s ≈ 7 GeV. By analyzing…

Multicomponent Superfluids and Superconductors in Dense Nuclear and Quark Matter

Matter at intermediate baryon densities and low temperatures is notoriously hard to tackle theoretically. Whereas lattice methods cannot cover more than rather small densities, perturbative methods…

Color deconfinement and subhadronic matter: phase states and the role of constituent quarks

- Physics
- 2004

Major aspects of the subhadronic state of nuclear matter populated with deconfined color particles are reviewed. At high and even at rather low nuclear collision energies, this is expected to be a…

Interplay of Mesonic and Baryonic Degrees of Freedom in Quark Matter

- Physics

In this work we study the influence of mesonic and baryonic fluctuations on the phase dia- gram of quark matter with two flavors. By examining the hadronization process and related techniques, we…

Joint Contour Net analysis of lattice QCD data

Lattice Quantum Chromodynamics (QCD) is an approach used by theo- retical physicists to model the strong nuclear force. This works at the sub-nuclear scale to bind quarks together into hadrons…

RADIATIVELY INDUCED VECTOR REPULSION FOR LIGHT QUARKS
