QCD-Thermodynamics using 5-dim Gravity

Understand

We calculate the critical temperature and free energy of the gluon plasma using the dilaton potential arXiv:0911.0627[hep-ph] in the gravity theory of AdS/QCD.

• The finite temperature observables are calculated in two ways: first, from the Page-Hawking computation of the free energy, and secondly using the Bekenstein-Hawking proportionality of the entropy with the area of the horizon.
• Renormalization is well defined, because the T=0 theory has asymptotic freedom.
• We further investigate the change of the critical temperature with the number of flavours induced by the change of the running coupling constant in the quenched theory.
