Quark–Gluon plasma and heavy-ion phenomenology.

Understanding the behaviour bulk matter governed by QCD elementary degrees of freedom and interaction, and studying how it turns into hadronic matter, offers challenging perspectives and touches fundamental issues in the study of QCD in its nonperturbative regime. This special issue of the European Journal of Physics: Special Topics entitled Quark–Gluon Plasma and heavy-ion phenomenology published a set of 7 papers aiming to put in perspective the important problems that are being addressed by the researchers in this area. The main motivation of this special issue is to learn the properties of the densest and hottest forms of QCD matter that one can produce in the laboratory. [ABSTRACT FROM AUTHOR]
