摘要:The coupling between elementary units,either weak or strong,determines the nature of matter controlled by different forces.As for three fundamental interactions(gravitational,electromagnetic,and strong),all the gauge bosons to mediate the forces are massless,and we may simply approximate the interaction energy at short distances with a Coulomb-like form of V=-αi/r,with r the separation between units.
