A remarkable consequence of the AdS/CFT correspondence is the nonperturbative derivation of dimensional counting rules for hard scattering processes. Using string/gauge duality we derive the QCD power behavior of light-front Fock-state hadronic wavefunctions for hard scattering in the large-r region of the AdS space from the conformal isometries which determine the scaling of string states as we approach the boundary from the interior of AdS space. The nonperturbative scaling results are obtained for spin-zero and spin-1/2 hadrons and are extended to include the orbital angular momentum dependence of the constituents in the Fock-expansion in the light-cone. Quark interchange amplitudes emerge as the dominant large N{sub c}scattering mechanisms for conformal QCD.

- Light-Front Dynamics and AdS/QCD Correspondence: The Pion Form Factor in the Space- and Time-Like Regions (2007, unknown): “This simple approach, which has been described as a “bottom-up” approach, has been successful in obtaining general properties of scattering amplitudes of hadronic bound states at strong coupling [2, 3, 4, 5], the low-lying hadron spectra [6, 7, 8, 9, 10, 11, 12, 13, 14, 15], hadron couplings and chi”
- Strongly correlated quantum fluids: ultracold quantum gases, quantum chromodynamic plasmas and holographic duality (2012, background): “(ii) Bottom up approach: In this approach, one looks at the hadron phenomenology of QCD first and then attempts to build its 5D-gravity equivalent model in AdS5 space-time by introducing appropriate fields and modifying the geometry of the extra dimension to reproduce the phenomenology [111, 112, 11”
- Light-front holographic QCD and emerging confinement (2014, unknown): “In one approach to AdS/QCD [67, 68, 69], bulk fields are introduced to match the SU(2)L×SU(2)R chiral symmetries of QCD and its spontaneous breaking, but without explicit connection with the internal constituent structure of hadrons [70].”
- Nonperturbative QCD coupling and its β function from light-front holography (2010, background): “[23] Instead, axial and vector currents become the primary entities as in an effective chiral theory.”
