The Fluxed MSSM
Recent developemnts in string compactifications in the presence of
antisymmetric field backgrounds suggest a new simple and predictive structure
for soft terms in the MSSM depending only on two parameters. They give rise to
a positive definite scalar potential, a solution to the -problem, flavor
universality and absence of a SUSY-CP problem.Comment: 23 pages, no figures. Addendum on intersecting D7-branes included.

dual superconductor models: the magnetic loop ensemble point of view
In this work, we initially discuss some physical properties of effective
YMH models, emphasizing the important role of
valence gluons. Next, we review how adjoint fields are naturally generated as
an effective description of "adjoint" loops in . Finally, we discuss the
consequences that can be learnt from this point of view, and briefly comment on
some improvements.Comment: 14 pages, 7 figures, proceedings of the XII Quark Confinement
