# Light-front hadron dynamics and AdS/CFT correspondence

@article{Brodsky2004LightfrontHD, title={Light-front hadron dynamics and AdS/CFT correspondence}, author={Stanley J. Brodsky and Guy F. de T{\'e}ramond}, journal={Physics Letters B}, year={2004}, volume={582}, pages={211-221} }

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… Expand
