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