QCD matter
Quark matter or QCD matter refers to any of a number of phases of matter whose degrees of freedom include quarks and gluons. These phases occur at extremely high temperatures and densities, billions of times higher than can be produced in equilibrium in laboratories. Under such extreme conditions, ..

QCD string
In quantum chromodynamics, or more generally, quantum gauge theories with a connection which are confining, stringlike degrees of freedom called QCD strings or QCD flux tubes form. These stringlike excitations are responsible for the confinement of color charges since they are always attached to at ..

QCD vacuum
The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non-perturbative vacuum state, characterized by many non-vanishing condensates such as the gluon condensate or the quark condensate. These condensates characterize the normal phase or the confined phase of quar..
