Query: Hadron Spectroscopy and Structure from AdS/CFT   The AdS/CFT correspondence between conformal field theory and string states
in an extended space-time has provided new insights into not only hadron
spectra, but also their light-front wavefunctions. We show that there is an
exact correspondence between the fifth-dimensional coordinate of anti-de Sitter
space and a specific impact variable which measures the separation of the
constituents within the hadron in ordinary space-time. This connection allows
one to predict the form of the light-front wavefunctions of mesons and baryons,
the fundamental entities which encode hadron properties and scattering
amplitudes. A new relativistic Schrodinger light-front equation is found which
reproduces the results obtained using the fifth-dimensional theory. Since they
are complete and orthonormal, the AdS/CFT model wavefunctions can be used as an
initial ansatz for a variational treatment or as a basis for the
diagonalization of the light-front QCD Hamiltonian. A number of applications of
light-front wavefunctions are also discussed.
