Toward a More Realistic Holographic QCD Model
Abstract
By matching the Dp-Dq system in type II superstring theory with the Regge trajectories of vector and axial-vector meson spectra, a possible 5-dimension metric of a Dp-Dq soft-wall model has been determined. The dependence of the metric parameters on Regge trajectory parameters has been demonstrated. It is shown that the models defined in Dp brane background for p = 3 or 4 can be consistent with experimental data.
