Description

A dilaton potential is adjusted to recently confirmed lattice QCD thermodynamics data in the temperature range (0.7.. 3.5)Tc where Tc = 155 MeV is the pseudocritical 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).
