标题： Particle states of Lattice QCD

摘要： 我们确定了产生零重子化学势下格点QCD压力和比熵的粒子的简并因子和平均粒子质量。 胶子和夸克的状态数在高于$T=$230 MeV时趋于接近常数值，接近理想夸克-胶子相的状态数，而它们的赋予质量保持较高值。 包含与胶子相互作用的夸克的系统的状态数和平均质量在$T \sim 150$到160 MeV之间随着温度的增加而急剧减少，该区域位于手征转变区域之内。 此温度区间内状态数的最小值表明这些状态具有强子性质。 显示英文摘要

摘要： We determine the degeneracy factor and the average particle mass of particles that produce the Lattice QCD pressure and specific entropy at zero baryon chemical potential. The number of states of the gluons and the quarks are found to converge above $T=$230 MeV to almost constant values, close to the number of states of an ideal Quark-Gluon Phase, while their assigned masses retain high values. The number of states and the average mass of a system containing quarks in interaction with gluons are found to decrease steeply with increase of temperature between $T \sim 150$ and 160 MeV, a region contained within the region of the chiral transition. The minimum value of the number of states within this temperature interval indicates that the states are of hadronic nature.
