高密度双色QCD

Two-color QCD at high density

Tamer Boz, Pietro Giudice, Simon Hands, Jon-Ivar Skullerud, Anthony G. Williams

摘要:

高化学势下的QCD具有有趣的性质,如夸克的解除禁闭。双色量子色动力学是在高化学势下研究量子色动力学的实验室,它可以在晶格上进行数值模拟。双色QCD在高密度的有趣的属性之一是双夸克凝聚,为此,我们提出了最近的结果相比,以前的研究在一个更精细的晶格。在非零化学势的双色QCD中,夸克传播子被称为哥可夫传播子。我们表示的Gor'kov传播的形状因子,并提出最近的晶格模拟结果。

英文摘要:

QCD at high chemical potential has interesting properties such as deconfinement of quarks. Two-color QCD, which enables numerical simulations on the lattice, constitutes a laboratory to study QCD at high chemical potential. Among the interesting properties of two-color QCD at high density is the diquark condensation, for which we present recent results obtained on a finer lattice compared to previous studies. The quark propagator in two-color QCD at non-zero chemical potential is referred to as the Gor'kov propagator. We express the Gor'kov propagator in terms of form factors and present recent lattice simulation results.
