چکیده
The thermodynamics of 5D dilaton gravity duals to confining gauge theories is analyzed. We show that they exhibit a first order Hawking-Page type phase transition. In the explicit background of improved holographic QCD of [U. Gursoy and E. Kiritsis, J. High Energy Phys. 02 (2008) 03210.1088/1126-6708/2008/02/032] [U. Gursoy, E. Kiritsis, and F. Nitti, J. High Energy Phys. 02 (2008) 01910.1088/1126-6708/2008/02/019], we find T_{c}=235 MeV. The temperature dependence of various thermodynamic quantities such as the pressure, entropy, and speed of sound is calculated. The results are in agreement with the corresponding lattice data.

Nonperturbative dynamics in the colour – magnetic QCD vacuum
In the deconfinement phase of QCD quarks and gluons interact with the dense stochastic colour–magnetic vacuum. We consider the dynamics of quarks in this deconfinement phase using the Field Correlators Method and derive an effective nonperturbative interquark potential, in addition to the usual perturbative short–ranged interaction. We find the resulting angular–momentum–dependent interaction t...
متن کاملRelation between color-deconfinement and chiral restoration
Quantum Chromodynamics (QCD) is believed to undergo phase transitions from hadronic matter to a quark-gluon plasma (QGP) at high temperature. The QGP phase transitions can consist of two distinct transitions – the deconfinement transition and the chiral phase transition. Several theoretical studies [1] have clarified that confinement would be closely related to chiral dynamics and the confined ...
متن کاملDeconfinement and Thermodynamics in 5D Holographic Models of QCD
We review 5D holographic approaches to finite temperature QCD. Thermodynamic properties of the “hard-wall” and the “soft-wall” models are derived. Various non-realistic features in these models are cured by the set-up of improved holographic QCD, that we review here.
متن کاملA remark on the large difference between the glueball mass and Tc in quenched QCD
The lattice QCD studies indicate that the critical temperature Tc ≃ 260 − 280 MeV of the deconfinement phase transition in quenched QCD is considerably smaller than the lowest-lying glueball mass mG ≃ 1500 − 1700 MeV, i.e., Tc ≪ mG. As a consequence of this large difference, the thermal excitation of the glueball in the confinement phase is strongly suppressed by the statistical factor as eGc ≃...
متن کاملTransverse momentum broadening of heavy quark and gluon energy loss in Sakai-Sugimoto model
In this paper, we calculate the transverse momentum diffusion coefficient κT of heavy quark and gluon penetration length in the deconfinement phase of Sakai-Sugimoto model, which is known as a holographic dual of large Nc QCD. We find that for the heavy quark moving through the thermal plasma with a constant velocity v < 1, the transverse momentum diffusion coefficient κT ∝ λγ 1 3 T /Td, and th...
