夸克-胶子等离子体中阿贝尔单极子的关联

Correlations of Abelian monopoles in quark-gluon plasma

V. V. Braguta, A. Yu. Kotov

摘要:

本文研究了SU(2)胶子动力学解禁闭阶段热阿贝尔单极的性质。特别地,为了研究QGP的Abel分量的性质,我们计算了$T/T_c \in (1.5, 6.8)$区域中不同温度下的单极子的三点关联函数。计算结果表明,三点关联函数可用单极子的独立对关联来描述。由此可以得出结论,QGP中的阿贝尔单极子系统揭示了稀气体的性质。此外,可以断言阿贝尔单极子之间的相互作用是对相互作用,并且在单极子之间不存在三粒子力。

英文摘要:

In this paper the properties of thermal Abelian monopoles in the deconfinement phase of the SU(2) gluodynamics are considered. In particular, to study the properties of the Abelian monopole component of QGP we calculate three-point correlation functions of monopoles for different temperatures from the region $T/T_c \in (1.5, 6.8)$. The results of the calculation show that the three-point correlation functions can be described by independent pair correlations of monopoles. From this one can conclude that the system of Abelian monopoles in QGP reveals the properties of a dilute gas. In addition, one can assert that the interaction between Abelian monopoles is a pair interaction and there are no three-particle forces acting between monopoles.
