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_-0.07^+0.04 GeV<m_G<1.36_-0.10^+0.05 GeV. In terms of a background dilaton field Φ(z)=cz², the two-point correlation function for the scalar gluon operator is obtained. The two-point correlation function at Δ=4 gives a different behavior compared with the one in QCD.
