Contribution

It systematically applies the GP to hadron properties, revealing the parameter hierarchy and providing insights into the success of simple models of hadrons.

Findings

Hierarchy of parameters explains model effectiveness

Clarifies current vs. constituent quark relationship

Provides detailed application to baryons and mesons

Abstract

After summarizing the basic points of the general QCD parametrization (GP) we discuss systematically its applications to the properties of the lowest families of baryons and mesons. We show how the hierarchy of the parameters in the GP emerges clearly in the properties of hadrons. Among other things, it explains why simple models can work reasonably well and clarifies the relationship between current and constituent quarks. More details on the hadron properties discussed with the GP appear from the list of secrions at the beginning of the paper.
