The critical point of lattice QCD on the μ-T plane
Abstract
We propose a method to study lattice QCD at finite temperature and chemical potential. We compare it with direct results and with the Glasgow method by using nf=4 QCD at Im(μ)≠ 0. We locate the critical endpoint (E) of QCD on the Re(μ)-T plane. In this study we use nf=2+1 dynamical staggered quarks with semi-realistic masses on Lt=4 lattices.
