Cross-over versus first-order phase transition in holographic gravity-single-dilaton models of QCD thermodynamics
Cross-over versus first-order phase transition in holographic gravity-single-dilaton models of QCD thermodynamics
Yaresko, R.; Knaute, J.; Kämpfer, B.
A dilaton potential is adjusted to recently confirmed lattice QCD thermodynamics data in the temperature range (0.7…3.5)Tc where Tc=155MeV is the pseudo-critical temperature. The employed holographic model is based on a gravity--single-field dilaton dual. We discuss conditions for enforcing (for the pure gluon plasma) or avoiding (for the QCD quark-gluon plasma) a first-order phase transition, but still keeping a softest point (minimum of sound velocity).
