A path to confine gluons and fermions through complex gauge theory

Description
Summary:We introduced here the study of a QCD based on a complex group. Our aim is to show that a gauge theory with a complex symmetry develops some of the features required for the description of a confined phase. This theory leads to gluons with propagations characteristic of i-particles, fundamental constituents of propagators in the Gribov scenario, together with a gluon propagating with the mode predicted by 't Hooft for the quark confinement. In this way, we present in this same theory a possible gluon condensate, together with a confining interquark potential after the coupling to fermions. This is a novelty, as, up to now, all theories of the GZ kind do not generate quark confinement.
