夸克禁闭与手征对称性破缺的关系

On the relation of quark confinement and chiral symmetry breaking

Jens Braun, Lisa M. Haas, Florian Marhauser, Jan M. Pawlowski

摘要:

我们利用手征对称性破缺和夸克禁闭的序参量研究了QCD的相图。我们还为禁闭相变引入了一个新的序参量,它与夸克密度有关。它很容易通过不同的理论方法,如功能的方法或晶格模拟。讨论了它与Polyakov环期望值的关系,并分析了QCD相图。我们的结果表明手征相变和限制相变之间有密切的关系。

英文摘要:

We study the phase diagram of QCD with the help of order parameters for chiral symmetry breaking and quark confinement. We also introduce a new order parameter for the confinement phase transition, which is related to the quark density. It is easily accessible by different theoretical approaches, such as functional approaches or lattice simulations. Its relation to the Polyakov loop expectation value is discussed and the QCD phase diagram is analysed. Our results suggest a close relation between the chiral and the confinement phase transition.
