手征凝聚和夸克数密度与静态夸克源的关联

Correlations of chiral condensates and quark number densities with static quark sources

Kay Huebner

摘要:

本文研究了在有限温度下具有手征凝聚和夸克数密度的Polyakov圈和静态介子/双夸克系统的关联函数。特别是后者的观察可以给洞察机制的筛选和字符串在有限的温度下断裂。我们分析了2+1味量子色动力学中产生的规范场位形,它具有近似物理的轻夸克质量和物理的奇异夸克质量,时间范围为Nt=4和6.

英文摘要:

We investigate correlation functions of the Polyakov loop and static meson/diquark systems with the chiral condensate and the quark number density at finite temperature. In particular the latter observable can give insight in the mechanism of screening and string breaking at finite temperature. We use for our analysis gauge field configurations generated in 2+1 flavor QCD with an improved staggered fermion action with almost physical light quark masses and a physical value of the strange quark mass on lattices with temporal extent Nt=4 and 6.
