Finite T/μlattice QCD and the critical point

Abstract

We present results on lattice QCD at finite temperature (T) and chemical potential (μ). We apply the overlap-improving multi-parameter reweighting technique for n_f=4 and 2+1 staggered QCD. We use semi-realistic masses on L_t=4 lattices. The critical endpoint (E) of 2+1 flavour QCD on the μ-T plane is located. Our results are based on {\cal{O}}(10^3-10^4) configurations.
