束缚型Dyon-Anti-Dyon库仑液体模型Ⅰ

Confining Dyon-Anti-Dyon Coulomb Liquid Model I

Yizhuang Liu, Edward Shuryak, Ismail Zahed

摘要:

我们重新讨论了Diakonov和Petrov讨论的杨-米尔斯封闭真空的双子-反双子液体模型,保留了由双子和反双子之间的流线介导的经典相互作用的影响。在SU(2)情形下,该模型描述了中心对称相的四组分强相互作用库仑液体。我们发现,在线性化屏蔽近似的流线相互作用产生Debye-Huckel型修正的体积参数,如压力和密度,但不改变显着的大距离行为的关联函数在领先的顺序。静态标量和带电结构因子与库仑参数为$Γ_{D\bar D}\approx 1$的双反双荷子液体在双反双荷子通道中的等离子体一致。重夸克仍然是线性限制的,大的空间威尔逊圈仍然表现出领先的面积定律。t $^\prime$ Hooft环被示出为1模库仑校正。

英文摘要:

We revisit the dyon-anti-dyon liquid model for the Yang-Mills confining vacuum discussed by Diakonov and Petrov, by retaining the effects of the classical interactions mediated by the streamline between the dyons and anti-dyons. In the SU(2) case the model describes a 4-component strongly interacting Coulomb liquid in the center symmetric phase. We show that in the linearized screening approximation the streamline interactions yield Debye-Huckel type corrections to the bulk parameters such as the pressure and densities, but do not alter significantly the large distance behavior of the correlation functions in leading order. The static scalar and charged structure factors are consistent with a plasma of a dyon-anti-dyon liquid with a Coulomb parameter $Γ_{D\bar D}\approx 1$ in the dyon-anti-dyon channel. Heavy quarks are still linearly confined and the large spatial Wilson loops still exhibit area laws in leading order. The t$^\prime$ Hooft loop is shown to be 1 modulo Coulomb corrections.
