Abstract:

The chiral phase transition of the quark matter is studied in the framework of the QCD-like gauge field theory. The thermodynamical potential is investigated using a variational approach. Latent heat generated in the first-order phase transition is calculated and it is shown that the latent heat is enhanced near the tricritical point and is more than several hundred MeV per quark.
