  Color Confinement under Color charge dipole and quadrupole moments

+ 5 like - 0 dislike

We know that in the Strong Nuclear force, color confinement limits the ability of color charges to separate too far. Since color charge separation grows the potential energy unboundedly, it reaches a vacuum breakdown limit, akin to the Schwinger limit for EM fields

But one could imagine a situation where color charge dipoles could become aligned inside hadrons of nuclear matter, and induce a color dipolar moment large enough to generate a macroscopic chromodynamic field. Color confinement shouldn't intervene to avoid this, since each quark is still confined: the field is just the results of many quarks aligned in a preferential way according to their color

Note that I am not sure of what would be the best way to induce such dipolar moments, but I wouldn't expect it to be impossible in principle: quarks are sensitive to electromagnetic fields, so a gamma-ray line energetic enough should be able to affect their distributions inside hadrons, affecting the populations of the excited quark dipolar states

My question to the experts on QCD and Yang-Mills theory is this: what would be some observational consequences of a macroscopic chromodynamic field induced by dipolar and quadrupolar moments of color charge?

Also, assuming the dipolar (or quadrupolar) moments can be induced, would it be a safe assumption to expect the chromodynamic fields to decay with cubic and quartic powers of distance, just as electric dipole and quadrupole fields?
