Meson Physics in the Quark Model.
Meson physics is studied in a relativistic quark model which includes the important features of quantum chromodynamics. It is found that all mesons from the (pi) to the (UPSILON) are described with reasonable success. The spectroscopic results of the model are supported by an extensive analysis of strong, electromagnetic, and weak meson couplings. The key ingredient of the model is a universal one-gluon-exchange plus linear confinement potential motivated by QCD, although the inclusion of relativistic effects is crucial to the success of the model. The analysis indicates that a successful theory of the strong interaction must be consistent with the general features expected from QCD.
