摘要: We show how the string amplitude {Phi}(z) defined on fifth dimension in AdS{sub 5} space can be precisely mapped to light-front wavefunctions of hadrons physical spacetime. find an exact correspondence between holographic variable z and impact {zeta}, which represents measure transverse separation constituents within hadrons. In addition, we derive effective four dimensional Schroedinger equations for bound states massless quarks gluons exactly reproduce AdS/CFT results give a realistic description light-quark meson baryon spectrum as well form factors spacelike Q{sup 2}. Only one parameter sets mass scale, {Lambda}{sub QCD}, is introduced.
