摘要
We propose a method to study lattice QCD at finite T and p,. We compare it with direct results and with the Glasgow method by using n(f)=4 QCD at Im(mu)not equal0. We locate the critical endpoint (E) of QCD on the Re(mu)-T plane. In this study we use n(f)=2+1 dynamical staggered quarks with semi-realistic masses on L-t = 4 lattices.
