Condensates, massive gauge fields, and confinement in the SU(3) gauge theory

Condensates, massive gauge fields, and confinement in the SU(3) gauge theory

Abstract 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 cho...

description Abstract 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
