For phenomenological reasons it must also transmit supersymmetry from the hidden to the visible sector in a dominantly flavor neutral manner. Also any such theory of supersymmetry breaking has to take into account the problem of quadratic divergences which arise once the theory is embedded in supergravity. A class of possible models that arise from GKP-KKLT type IIB string compactifications, incorporating all this while being consistent with gauge unification, with just the bare minimum of necessary supergravity/string theory moduli fields coupled to the minimally supersymmetric standard model, is presented. Such models give reasonable values for the soft masses, the $μ$ and $Bμ$ terms and the gaugino masses. Assuming that an actual detailed realization exists, it is very likely that they are the simplest such possibility .Minor revisions.
