Abstract: | 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. |
