Confinement Driven by Scalar Field in 4d Non Abelian Gauge Theories.

We review some of the most recent work on confinement in 4d gauge theories with a massive scalar field (dilaton). Emphasis is put on the derivation of confining analytical solutions to the Coulomb problem versus dilaton effective couplings to gauge terms. It is shown that these effective theories can be relevant to model quark confinement and may shed some light on confinement mechanism. Moreover, the study of interquark potential, derived from Dick Model, in the heavy meson sector proves that phenomenological investigation of this mechanism is more than justified and deserves more efforts. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
