National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Light-Front Hadron Dynamics and AdS/CFT Correspondence.

DE2004826465

Publication Date	2003
Personal Author	Brodsky, S. J.; de Teramond, G. F.
Page Count	18
Abstract	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 larger 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 NC scattering mechanisms for conformal QCD.
