Comparison of the AdS/QCD prediction for the orbital and radial excitations of the meson spectrum with experiment. The pion is predicted to be massless for zero quark mass. The quark masses can be taken into account by perturbing in . The fitted value of GeV for pseudoscalar mesons, and GeV for vector mesons.
