The contribution due to the chiral meson exchange to the energy levels of the light baryons is studied in the constituent quark model. The effects of different dynamical ingredients are discussed and the results with and without the chiral meson exchange are compared. Our calculation accommodates all confirmed states and indicates that the chiral meson exchange is indeed necessary to resolve some outstanding problems.

Counting Rules

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.
