摘要

我们提出了一种在有限温度(T)和化学势(μ)下研究晶格QCD的方法。我们对该方法进行了测试，并使用虚μ的nf = 4交错QCD与Glasgow方法进行了比较。确定了QCD在Re(μ) -T平面上的临界端点E。我们在Lt = 4晶格上使用nf = 2 + 1具有半真实质量的动态交错夸克。我们的结果是基于\({\mathcal{O}}\)(103 - 104)配置。

Lattice QCD results at finite T and μ

We propose a method to study lattice QCD at finite temperature (T) and chemical potential (μ). We test the method and compare it with the Glasgow method using nf = 4 staggered QCD with imaginary μ. The critical endpoint (E) of QCD on the Re(μ) —T plane is located. We use nf = 2 + 1 dynamical staggered quarks with semi-realistic masses on Lt = 4 lattices. Our results are based on \({\mathcal{O}}\)(103 – 104) configurations.
