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