Abstract

The Anti-de Sitter Space/Conformal Field Theory (AdS/CFT) correspondence may offer new and useful insights into the non-perturbative regime of strongly coupled gauge theories such as Quantum Chromodynamics (QCD). A modified soft-wall AdS/QCD model is constructed to incorporate both explicit and spontaneous chiral symmetry breaking and linear confinement. This model contains a modified dilaton and higher-order interaction terms in the Lagrangian. Within this model we calculate the radial scalar, pseudo-scalar, vector and axial- vector mass spectra.We find good agreement with experimental data. We show how to construct potentials which lead to such solutions.
