Constraining the Infrared Behavior of the Soft-Wall AdS/QCD Model
arXiv:1105.6293 · doi:10.1103/PhysRevD.85.094021
Abstract
By requiring the correct Regge behavior in both meson and nucleon sectors, we determine the infrared asymptotic behavior of various background fields in the soft-wall AdS/QCD model, including the dilaton, the warp factor, and the scalar VEV. We then use a simple parametrization which smoothly connect these IR limits and their usual UV limits. The resulting spectrum is compared with experimental data, and the agreement between them is good.
