Abstract

The scalar glueball is investigated in a soft-wall model of AdS/QCD. Constraints of the mass of the scalar glueball are given through an analysis of a relation between the bulk mass and the anomalous dimension. The mass of the ground scalar glueball is located at $0.96^{+0.04}_{-0.07} \rm{GeV}<m_G<1.36^{+0.05}_{-0.10}\rm{GeV}$ . In terms of a background dilaton field $\Phi(z)=cz^2$ , the two-point correlation function for the scalar gluon operator is obtained. The two-point correlation function at $\Delta=4$ gives a different behavior compared with the one in QCD.
