部分子的色单态成团和夸克-胶子等离子体强子化的复合模型

Colour-singlet clustering of partons and recombination model for hadronization of quark-gluon plasma

Raktim Abir, Munshi G. Mustafa

摘要:

$SU(N_c)$色单重态限制,以及味和自旋对称性,对热部分子系综被证明重组的部分子与内部颜色结构成色单重态多夸克集团,可以确定在一个给定的温度下的各种强子模式。这为夸克-胶子等离子体强子化的复合模型提供了可能的基础。这也导致一个自然的解释(反)质子的比例,介子和夸克数标度的椭圆流系数在相对论性重离子碰撞。

英文摘要:

$SU(N_c)$ colour-singlet restriction, along with flavour and spin symmetry, on thermal partonic ensemble is shown to recombine the partons with internal colour structure into colour-singlet multi-quark clusters which can be identified with various hadronic modes at a given temperature. This provides a possible basis for recombination model for hadronization of quark-gluon plasma. This also leads to a natural explanation for the ratio of (anti)protons to pions and the quark number scaling of the elliptic flow coefficient in relativistic heavy-ion collisions.
