Description
In the general framework of phenomenological KKLT-like models in supergravity setup, I will talk about the case where the uplift to a Minkowski vacuum is provided by a Fayet-Iliopoulos sector in the presence of an extra anomalous U(1) symmetry. The modulus contribution to supersymmetry breaking is larger than in the models already present in the literature and a new mixed gauge-gravity mediation appears in some explicit examples. This provides an original phenomenology in principle testable at LHC, where the whole superpartner spectrum can be efficiently compressed at low-energy and sleptons are generically heavier than squarks.
