Query: A Realistic Unified Gauge Coupling from the Micro-Landscape of Orbifold
  GUTs   We consider 5-dimensional supersymmetric field theories where supersymmetry
is broken by the Scherk-Schwarz mechanism (or, equivalently, by the F-term VEV
of the radion). In such models, the radion effective potential is calculable in
terms of the 5d gauge coupling, the UV cutoff of the 5d field theory, and the
field content. We provide simple, explicit formulae for the leading part of the
two-loop effective potential. Our analysis applies in particular to 5d orbifold
GUTs motivated by heterotic orbifold models. We focus on potentially realistic
models of this type and make the additional assumption that the UV cutoff scale
is identical with the strong-coupling scale of the 5d gauge theory. Given our
stabilization mechanism, the 5d radius is now fixed in terms of the 5d gauge
coupling and the field content of the model. This implies a prediction for the
effective 4d gauge coupling only in terms of the field content of the model.
Given the `micro-landscape' provided by the different possible distributions of
Standard Model fields between bulk and branes, we find a subset of models with
a realistic unified gauge coupling. We also discuss two possibilities for the
`uplifting' of our SUSY-breaking AdS vacua: One is based on the possible
presence of a weak warping, the other appeals to F-terms in an extra
brane-localized SUSY-breaking sector.
