Abstract

We study the chiral phase transition in the linear sigma model at nonzero temperature and baryon density with Nf ≥ 3 quark flavours and Nc colours. One-loop calculations for Nf = 3 predict a first-order phase transition at both µ = 0 and µ/=0. We also compare the results with the already existing results for Nf = 2.

Keywords

linear sigma model; restoration of chiral symmetry; temperature; baryon density; three flavours
