Sažetak
We study the chiral phase transition in the linear sigma model at nonzero temperature and baryon density with $N_fgeq 3$ quark flavours and $N_c$ colours. One-loop calculations for $N_f =3$ predict a first-order phase transition at both $mu=0$ and $mu eq 0$. We also compare the results with the already existing results for $N_f =2$.
