QCD matter

Quark matter or QCD matter refers to any of a number of hypothetical phases of matter built from quarks and gluons, of which the prominent example is quark-gluon plasma. At different temperatures and
Particle debris trajectories from one of the first lead-ion collisions with the LHC, as recorded by the ALICE detector. The extremely brief appearance of quark matter in the point of collision is inferred from the statistics of the trajectories.
Quark star

A quark star is a hypothetical type of compact, exotic star, where extremely high core temperature and pressure have forced nuclear particles to form quark matter, a continuous state of matter consist
QCD matter
…it is reasonable to surmise that quark matter may exist in the core. Hypothetical compact stars composed mostly or entirely of quark matter are called quark stars or strange stars. QCD matter may exist within the collapsar of a gamma-ray burst, where temperatures as high as 6.7 × 1013 K may be generated…
