It was conjectured some time ago that an effective description of the
Coulomb-confinement transition in compact U(1) lattice gauge field theory could
be described by scalar QED obtained by soft breaking of the N=2 Seiberg-Witten
model down to N=0 in the strong coupling region where monopoles are light. In
two previous works this idea was presented at a qualitative level. In this work
we analyze in detail the conjecture and obtain encouraging quantitative
agreement with the numerical determination of the monopole mass and the dual
photon mass in the vicinity of the Coulomb to confining phase transition.Comment: 14 pag, 5 figure
