Energy Density in Quark Gluon Plasma

We study the energy density in quark-gluon plasma. At the very high temperature, the quark matter is a hot and dense matter in the color deconfinement condition, and quarks can coalescent diquarks. Energy density of this system is figured out and compared with the energy density in the other two kinds of situations. Possible energy density is about ε₀ ≈ 2.4 GeV/fm³ according to our estimation for quark matter including diquarks.
