Lattice QCD results at finite T and μ

Abstract

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.
