Moduli stabilization and uplifting with dynamically generated F-terms
We use the F-term dynamical supersymmetry breaking models with metastable vacua in order to uplift the vacuum energy in the KKLT moduli stabilization scenario. The main advantage compared to earlier proposals is the manifest supersymmetric treatment and the natural coexistence of a TeV gravitino mass with a zero cosmological constant. We argue that it is generically difficult to avoid anti de-S...
متن کاملde Sitter vacua from uplifting D - terms in effective supergravities from realistic strings
We study the possibility of using the D-term associated to an anomalous U(1) for the uplifting of AdS vacua (to dS or Minkowski vacua) in effective supergravities arising from string theories, particularly in the type IIB context put forward by Kachru, Kallosh, Linde and Trivedi (KKLT). We find a gauge invariant formulation of such a scenario (avoiding previous inconsistencies), where the anoma...
متن کامل- th ] 5 S ep 2 00 8 Sequestering in models of F - term uplifting ∗ Hiroyuki Abe
We discuss the nature of sequestering supersymmetry breaking sectors in a certain class of moduli stabilization in supergravity/string models, where a negative vacuum energy of the nonperturbative moduli potential is canceled by dynamically generated F-terms. Two illustrating examples are shown to sketch the issues around the supersymmetry breaking, flavors and sequestering within such a framew...
متن کاملP-term, D-term and F-term inflation
P-term inflation is a version of hybrid inflation which naturally appears in some brane inflation models. It was introduced in the framework of N=2 supersymmetric gauge theory where superconformal SU(2, 2|2) symmetry is broken down to N=2 supersymmetry by the vev of the auxiliary triplet field ~ P . Depending on the direction of this vev, one can get either D-term inflation or F-term inflation ...
متن کاملSp(N) higher-derivative F-terms via singular superpotentials
We generalize the higher-derivative F -terms introduced by Beasley and Witten [1] for SU(2) superQCD to Sp(nc) gauge theories with fundamental matter. We generate these terms by integrating out massive modes at tree level from an effective superpotential on the chiral ring of the microscopic theory. Though this superpotential is singular, its singularities are mild enough to permit the unambigu...
