5D中的通用仪表调解

General Gauge Mediation in 5D

Moritz McGarrie, Rodolfo Russo

摘要:

我们使用“通用规范调解”形式主义来描述一个5D设置与$S^{1}/Z_{2}$ orbifold。我们首先考虑一个模型独立的超对称性打破隐藏部门的一个边界和一般的手征物质的另一个。使用GGM的定义,隐藏扇区的影响包含在一组全局对称电流相关函数中,并通过批量进行调解。我们发现高吉诺,sfermion和超标量质量公式的最小和广义的信使在不同的制度的大,小和中间额外的维度。然后,我们使用5D GGM形式化构造了一个模型,其中SU(5)ISS模型位于隐藏边界上。我们弱规范的ISS模型的全球对称性,并将其与散装矢量超场。与4D GGM相比,有一种自然的方式通过因子$(M l)^{2}$来调整Gaugino与sfermion的质量比,其中M是SUSY断裂扇区的特征质量尺度,l是额外维度的长度。

英文摘要:

We use the "General Gauge Mediation" formalism to describe a 5D setup with an $S^{1}/Z_{2}$ orbifold. We first consider a model independent SUSY breaking hidden sector on one boundary and generic chiral matter on another. Using the definition of GGM, the effects of the hidden sector are contained in a set of global symmetry current correlator functions and is mediated through the bulk. We find the gaugino, sfermion and hyperscalar mass formulas for minimal and generalised messengers in different regimes of a large, small and intermediate extra dimension. Then we use the 5D GGM formalism to construct a model in which an SU(5) ISS model is located on the hidden boundary. We weakly gauge a global symmetry of the ISS model and associate it with the bulk vector superfield. Compared to 4D GGM, there is a natural way to adjust the gaugino versus sfermion mass ratio by a factor $(M l)^{2}$, where M is a characteristic mass scale of the SUSY breaking sector and l is the length of the extra dimension.
