A Potential for Soft-Wall AdS/QCD

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. Soft-wall AdS/QCD models reproduce the linear Regge trajectories of meson spectra by including background dilaton and chiral condensate fields. Efforts to derive these background fields from a gravitational potential have so far failed to correctly incorporate chiral symmetry breaking. We present a three-field scalar potential that includes the dilaton field and the chiral and glueball condensates. This potential is shown to satisfy both the UV boundary conditions on the background fields set by the AdS/CFT correspondence and the correct behavior in the IR limit to obtain spontaneous chiral symmetry breaking. We present the mass spectra produced by this model for the radially excited states of spin-0 and spin-1 mesons.
