摘要：
The purpose of this paper is to further study the soft-wall AdS/QCD model with constrained IR background proposed in [1]. By including a quartic bulk scalar potential we study various meson and nucleon spectra. This model naturally realizes the asymptotical linearity of these mass spectra simultaneously, together with correct patterns of explicit and dynamical chiral symmetry breaking. The agreement between the theoretical calculations and the experimental data is good.
