[en] In this paper we present a model for the dynamics of a gauge field theory such that spin-one particles can be confined in a compact domain. We show that the property of confinement can be associated to the formation of a null surface identified to a horizon. This is due the presence of an effective geometry generated by the self-interaction of the gauge field that guides the wave propagation of the field. This phenomenon has a striking analog to the gravitational back hole in Einstein general theory of relativity, separating two domains of spacetime that can be trespassed only into one direction.
