We study the chiral phase transition in the linear sigma model with 2 quark flavors and N c colors. One-loop calculations predict a first-order phase transition at both µ = 0 and µ ≠ 0. We also discuss the phase diagram and make a comparison with a thermal parametrization of existing heavy-ion experimental data.
