TL;DR

This paper explores the mass spectra of scalar and vector glueballs using a holographic AdS/QCD model with a dilaton background, analyzing how perturbations affect the glueball masses.

Contribution

It introduces a holographic model with a static dilaton background to study glueball spectra and examines the effects of perturbations on the model's mass predictions.

Findings

Mass spectra depend on dilaton and geometry perturbations

Constraints on glueball masses from holographic model

Insights into non-perturbative QCD phenomena

Abstract

We investigate the mass spectra of scalar and vector glueballs in the so-called bottom-up approach of the AdS/QCD correspondence. The holographic model of QCD includes a static dilaton background field. We study the constraints on the masses coming from perturbing the dilaton field and the geometry of the bulk.
