ON ELECTRODYNAMICS OF CONSTITUENT QUARKS AND QCD POTENTIAL

It is supposed that constituent quarks are confined objects. We derive Dirac and Maxwell equations for these quasiparticles from the condition that translation in-variance is broken. It is found that the modified electrostatic potential has exactly a form of the well-known strong (QCD) potential. Thus, it is shown that confinement may cause modification of physical laws and the QCD potential can be considered as a new evidence of constituent quarks inside the proton.
