Scalar glueball in a soft-wall model of AdS/QCD

  • 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<mG<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.

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<mG<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.
