abstract
Recently a holographic model of hadrons motivated by AdS/CFT has been proposed to fit the low energy data of mesons. We point out that the infrared physics can be developed in a more systematic manner by exploiting backreaction of the nonperturbative condensates. We show that these condensates can naturally provide the IR cutoff corresponding to confinement, thus removing some of the ambiguities from the original formulation of the model. We also show how asymptotic freedom can be incorporated into the theory, and the substantial effect it has on the glueball spectrum and gluon condensate of the theory. A simple reinterpretation of the holographic scale results in a non-perturbative running for alpha_s which remains finite for all energies. We also find the leading effects of adding the higher condensate into the theory. The difficulties for such models to reproduce the proper Regge physics lead us to speculate about extensions of our model incorporating tachyon condensation.

Neural networks trained on rho, a1, a2 and f0 mass spectra reconstruct a holographic QCD background with scalar potential k1 X^3 + k2 X^4 (k1 ~ -8, k2 ~17) and claim a pion-mass prediction that is partly circular.
Holographic AdS/QCD calculations of configurational entropy and complexity for Delta baryons yield Regge trajectories that organize known masses and predict additional resonances.
