  Even though quantum chromodynamics is a broken conformal theory, the AdS/CFT
correspondence has led to important insights into the properties of QCD. For
example, as shown by Polchinski and Strassler, dimensional counting rules for
the power-law falloff of hadron scattering amplitudes follow from dual
holographic models with conformal behavior at short distances and confinement
at large distances. We find that one also obtains a remarkable representation
of the entire light-quark meson and baryon spectrum, including all orbital
excitations, based on only one mass parameter. We also show how hadron
light-front wavefunctions and hadron form factors in both the space-like and
time-like regions can be predicted.
