摘要：We propose a method to study lattice QCD at nite temperature and chemical
potential. We compare it with direct results and with the Glasgow method by using
nf=4 QCD at Im()6 =0. We locate the critical endpoint (E) of QCD on the Re()-
T plane. In this study we use nf=2+1 dynamical staggered quarks with semi-realistic
masses on Lt=4 lattices.
