Spontaneous supersymmetry breaking with anomalous U(1) symmetry in metastable vacua and moduli stabilization
- Department of Physics, Nagoya University, Nagoya 464-8602 (Japan)
We show that in (anomalous) U(1) gauge theories with the Fayet-Iliopoulos term and with generic interactions, there are metastable vacua in which supersymmetry (SUSY) is spontaneously broken even without U(1){sub R} symmetry. In this vacua, various hierarchical structures such as Yukawa hierarchy can be explained by the smallness of the Fayet-Iliopoulos parameter. It is shown that, by adding just one positively charged field to phenomenologically viable models, spontaneous SUSY breaking is realized. Moreover, we propose a new scenario for the stabilization of the moduli in the SUSY breaking models. It is a new feature that the moduli can be stabilized without the superpotential being dependent on them.
