Abstract:
The QCD equation of state at finite baryon density is studied in the framework of a Cluster Expansion Model (CEM), which is based on the fugacity expansion of the net baryon density. The CEM uses the two leading Fourier coefficients, obtained from lattice simulations at imaginary mu(B), as the only model input and permits a closed analytic form. Excellent description of the available lattice data at both mu(B) = 0 and at imaginary mu(B) is obtained. We also demonstrate how the Fourier coefficients can be reconstructed from baryon number susceptibilities.
