   The mathematical derivation utilized the renormalization group equations, demonstrating that for non-Abelian gauge theories with a sufficiently small number of quark flavors ($n_f < 17$), the $\beta$-function, which governs the running of the coupling constant, is negative. This contrasts sharply with Quantum Electrodynamics (QED, where the coupling strengthens at high energies.
   The observation of asymptotic freedom provided the theoretical underpinning for the quark model, explaining why quarks inside hadrons appear nearly free when probed at high energie…
