QCD phase transition at real chemical potential with canonical approach

We study the finite density phase transition in the lattice QCD at real chemical potential. We adopt a canonical approach and the canonical partition function is constructed for Nf = 2 QCD. After derivation of the canonical partition function we calculate observables like the pressure, the quark number density, its second cumulant and the chiral condensate as a function of the real chemical potential. We covered a wide range of temperature region starting from the confining low to the deconfining high temperature; 0.65Tc ≤ T ≤ 3.62Tc. We observe a possible signal of the deconfinement and the chiral restoration phase transition at real chemical potential below Tc starting from the confining phase. We give also the convergence range of the fugacity expansion.
