Soft wall model in the hadronic medium

Abstract

We study the holographic QCD in the hadronic medium by using the soft wall model. We discuss the Hawking-Page transition between Reissner-Nordstr\"om anti-de Sitter (AdS) black hole and thermal charged AdS of which the geometries correspond to deconfinement and confinement phases, respectively. We also present the numerical result of the vector and axial-vector meson spectra depending on the quark density.
