| Abstract: | The generalization of QCD motivated classical SU(2) Yang-Mills theory coupled to a scalar field is discussed. The massive scalar field, corresponding to the scalar glueball,
provides a confining potential for static, point-like, external sources. In the case of a massless scalar field screening
solutions are found. However, there is a confining sector as well. Both, massive and massless confining solutions, are compared
with phenomenological potentials. The case of a non-dynam
ical permittivity is also discussed.
