夸克-胶子动力学中的QCD相边界

The QCD Phase Boundary from Quark-Gluon Dynamics

Jens Braun

摘要:

我们利用泛函重整化群研究了有限温度和有限化学势下的单味QCD。我们从夸克和胶子的角度讨论了QCD中的手征相变及其序和它的机制,并分析了小夸克化学势对相变温度的依赖关系。我们的结果的曲率相边界在小夸克化学势依赖于只有一个单一的输入参数,在Z质量尺度的强耦合的值。

英文摘要:

We study one-flavor QCD at finite temperature and chemical potential using the functional renormalization group. We discuss the chiral phase transition in QCD and its order with its underlying mechanism in terms of quarks and gluons and analyze the dependence of the phase transition temperature on small quark chemical potentials. Our result for the curvature of the phase boundary at small quark chemical potential relies on only a single input parameter, the value of the strong coupling at the Z mass scale.
