SOME ASPECTS OF GEOMETRICAL CONFINEMENT

In this paper we present a toy model for the dynamics of a gauge field theory in such a way that spin-one particles can be confined in a com pact domain. We show that the property of confinement can be associate d to the formation of a null surface identified to a horizon. This is due to the presence of an effective geometry generated by the self-int eraction of the gauge field that guides the wave propagation of the fi eld. This phenomenon has a striking analogy to the gravitational black hole in Einstein's general theory of relativity, separating two domai ns of space-time that can be trespassed only into one direction.
