Holographic prediction for the deconfinement temperature

We argue that deconfinement in anti-de Sitter space models of quantum chromodynamics (AdS/QCD models) occurs via a first order Hawking-Page type phase transition between low temperature thermal AdS and a high temperature black hole. Such a result is consistent with the expected temperature independence, to leading order in 1/N-c, of the meson spectrum and spatial Wilson loops below the deconfinement temperature. As a by-product, we obtain model dependent deconfinement temperatures T-c in the hard- and soft-wall models of AdS/QCD. Our result for T-c in the soft-wall model is close to a recent lattice prediction.
