Study of lattice QCD at finite baryon density using the canonical approach

Abstract

At finite baryon density lattice QCD first-principle calculations can not be performed due to the sign problem. In order to circumvent this problem, we use the canonical approach, which provides reliable analytical continuation from the imaginary chemical potential region to the real chemical potential region. We briefly present the canonical partition function method, describe our formulation, and show the results, obtained for two temperatures: $T/T_c=0.93$ and $T/T_c=0.99$ in lattice QCD with two flavors of improved Wilson fermions.
