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 n f = 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; 0.65t c ≤ t ≤ 3.62t c . we observe a possible signal of the deconfinement and the chiral restoration phase transition at real chemical potential below t c starting from the confining phase. we give also the convergence range of the fugacity expansion.
