Exploring Quark Distributions and Evolution Equations in Strong Interactions

This study delves into frequently used expressions in leading quark distributions, QCD evolution, and flavor singlet combinations, with coupled equations for evolution. Data from CERN, SLAC, and HERMES are analyzed, along with the isotopic SU(2) invariance of strong interactions. The research presents sum rules and experiment findings, highlighting the determination of varied elements as matrix elements of conserved currents. The intriguing Spin "puzzle" is also discussed.
