                  | アブストラクト: | String/gauge theory duality, assuming a truncated AdS/CFT space, gives a remarkable description of the light-quark hadron spectrum of QCD, as well as predicting the form of light-front Fock-state hadronic wavefunctions at short distances. The resulting light-front Fock-state wavefunctions provide a frame-independent representation of hadrons at the amplitude level in terms of their fundamental quark and gluon
degrees of freedom. Given the LFWFs, one can compute form factors, heavy-hadron decay amplitudes, hadron distribution amplitudes, and the generalized parton distributions underlying deeply virtual Compton scattering. The AdS/CFT correspondence thus has important implications for hadron phenomenology in the conformal limit, including an all-orders derivation of counting rules for exclusive processes. |  |
