有限温度和密度下QCD的约束性质

Confining properties of QCD at finite temperature and density

Simone Conradi, Alessio D'Alessandro, Massimo D'Elia

摘要:

用一个检测真空双超导电性的无序参量作为探针,表征了有限温度和密度下双色QCD相图的封闭性质。我们得到的证据消失的双重超导(解除禁闭)引起的重子物质的有限密度,以及为巧合的这种现象与恢复手征对称性在零和有限密度。研究了泡利阻塞引起的饱和跃迁,并对这种非物理跃迁可能对强规范耦合下QCD相图的研究产生的影响提出了一般性的警告。

英文摘要:

A disorder parameter detecting dual superconductivty of the vacuum is used as a probe to characterize the confining properties of the phase diagram of two color QCD at finite temperature and density. We obtain evidence for the disappearing of dual superconductivity (deconfinement) induced by a finite density of baryonic matter, as well as for a coincidence of this phenomenon with the restoration of chiral symmetry both at zero and finite density. The saturation transition induced by Pauli blocking is studied as well, and a general warning is given about the possible effects that this unphysical transition could have on the study of the QCD phase diagram at strong values of the gauge coupling.
