超对称破缺规范调解的广义信使扇区和软谱

Generalized messenger sector for gauge mediation of supersymmetry breaking and the soft spectrum

D. Marques

摘要:

我们考虑一个通用的可重正化和规范不变的信使部门,并推导出sparticle质谱使用的形式主义介绍了一般规范调解。我们的结果恢复了许多表达式中发现的文献中的各种限制。约束信使部门与全球对称性下的spurion场是收费的,我们分析超出小超对称性破缺极限的非凡规范调解。最后,我们包括D项贡献并计算它们对软质量的修正。这导致了一个微扰框架,允许探索能够完全覆盖超对称标准模型的参数空间的模型。

英文摘要:

We consider a generic renormalizable and gauge invariant messenger sector and derive the sparticle mass spectrum using the formalism introduced for General Gauge Mediation. Our results recover many expressions found in the literature in various limits. Constraining the messenger sector with a global symmetry under which the spurion field is charged, we analyze Extraordinary Gauge Mediation beyond the small SUSY breaking limit. Finally, we include D-term contributions and compute their corrections to the soft masses. This leads to a perturbative framework allowing to explore models capable of fully covering the parameter space of General Gauge Mediation to the Supersymmetric Standard Model.
