DUAL MEISSNER EFFECT IN THE INFRARED REGION OF QCD WITH QUARKS

Abstract

Motivated by the suggestion of 't Hooft and Mandelstam that magnetic monopoles must play a crucial role in the ir region of QCD and that of Nambu that dual Meissner effect as a mechanism of confinement, QCD in this region is described by the magnetic symmetry of Cho. The standard SU(3) QCD action with quarks is considered which now contains the monopole configurations. A dual action is constructed and mass term for the dual Abelian field is generated by gauge mixing mechanism. The effective dual action thus obtained exhibits dual Meissner effect.
