Glueballs as gravitons in holographic approaches

Abstract

In this contribution we present a a phenomenological analysis of the scalar glueball and scalar meson spectra within AdS/QCD models in the bottom-up approach. In particular, we consider a Light-Front QCD framework which allows to relate the AdS/QCD mode functions to the hadronic wave-functions. Such a procedure is here adopted to analyse the mixing between scalar mesons and glueballs.
