It appears that the fundamental interactions of nature which are electromagnetic, strong and weak interactions are gauge type. The following analysis basically concerns quantum chromodynamics(QCD) which is a non-abelian gauge theory that respects the gauge symmetry of the SU(3) group. Although in Qu...
