In-medium hadronic spectral functions through the soft-wall holographic model of QCD

Abstract

We study the scalar glueball and vector meson spectral functions in a hot and dense medium by means of the soft-wall holographic model of QCD. Finite temperature and density effects are implemented through the AdS/RN metric. We analyse the behaviour of the hadron masses and widths in the $(T,\mu )$ plane, and compare our results with the experimental ones and with other theoretical determinations.
