非最小规范调解与模镇定

Non-minimal Gauge Mediation and Moduli Stabilization

T. Jelinski, Z. Lalak, J. Pawelczyk

摘要:

本文考虑了U(1)规范的双激励耦合到一个扭闭弦模的Polony模型。这为亚稳态超对称性击穿提供了一个一致的设置,允许模量稳定,并自然导致规范或混合规范/引力调解机制。由于第二个spurion的存在,我们可以在一个修正的Giudice-Masiero机制中安排μ和B_μ问题的解,该机制既适用于纯规范介导的极限,也适用于混合介导的混合区域。

英文摘要:

In this paper we consider U(1)-gauged Polony'i model with two spurions coupled to a twisted closed string modulus. This offers a consistent setup for metastable SUSY breakdown which allows for moduli stabilization and naturally leads to gauge or hybrid gauge/gravitational mediation mechanism. Due to the presence of the second spurion one can arrange for a solution of the μand B_μproblems in a version of modified Giudice-Masiero mechanism, which works both in the limit of pure gauge mediation and in the mixed regime of hybrid mediation.
