General form of color charge of the quark

Abstract: In Maxwell theory the constant electric charge e of the electron is consistent with the continuity equation ∂ µ j µ (x) = 0 where j µ (x) is the current density of the electron where the repeated indices component of a corresponding current density by integrating over the entire (physically) allowed volume, the color charge q a (t) of the quark in Yang-Mills theory is time dependent. In this paper we derive the general form of eight time dependent fundamental color charges q a (t) of the quark in Yang-Mills th… Show more

“…(21) we find that the light-like eikonal current produces pure gauge field in quantum field theory at all space-time points except at the positions perpendicular to the direction of motion of the charge at the time of closest approach, a result which agrees with the classical mechanics [41,49,50]. Hence we find from Eq.…”

“…Hence, in some later works (see, for example, [55,56]) it was shown that perturbative predictions in QCD agree well with phenomenological QCD results (determined from heavy quarkonium spectroscopy) and lattice QCD calculations. For recent developments on color potential produced by the color charge of the quark, see [49,50].…”

“…The light-like quark traveling with light-like four-velocity l µ produces SU(3) pure gauge field A µc (x) both in classical mechanics [21][22][23] and in quantum field theory [24] at all the timespace position x µ except at the position x perpendicular to the direction of motion of the quark ( l · x = 0) at the time of closest approach (x 0 = 0). When A µc (x) = A µc (λl) as in eq.…”
