Abstract
In models where supersymmetry-breaking is dominated by the Kähler moduli and/or the universal dilaton, the B-parameter at the unification scale should be consistent with the value of tanβ at the electroweak scale determined by minimization of the Higgs potential triggering REWSB. We study such models employing a self-consistent determination of the B-parameter. In particular, we study the viability of a generic model, as well as M-theory and Type IIB flux compactifications with modulus-dominated supersymmetric soft-terms from the GUT scale, MGUT=2×1016 GeV.
Highlights
If TeV-scale supersymmetry is discovered at LHC, it will open a window in which to explore physics at higher-energy scales
We conclude that modulus-dominated supersymmetry breaking is not viable, in the case of a standard Renormalization Group Equations (RGEs) running of the soft terms starting from the GUT scale
A well-motivated framework for studying supersymmetry breaking is to assume that it is dominated by the Kahler moduli and/or the universal dilaton
