摘要：
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 anti-de Sitter/QCD model, including the dilaton, the warp factor, and the scalar vacuum expectation value. We then use a simple parametrization which smoothly connects these IR limits and their usual UV limits. The resulting spectrum is compared with experimental data, and the agreement between them is good.
