SU(3) gauge theory in the nonlinear gauge of the Curci–Ferrari type is studied. In the low-energy region, ghost condensation and subsequent gauge field condensation can happen. The latter condensation makes classical gauge fields massive. If the color electric potential with a string is chosen as the classical gauge field, it produces the static potential with the linear potential. We apply this static potential to the three-quark system, and show, differently from the Y-type potential, that infrared divergence remains in the Δ-type potential. The color electric flux is also studied, showing that a current which plays the role of the magnetic current appears |
