规范轴子的残余密度与超对称性

Relic Densities of Gauged Axions and Supersymmetry

Claudio Coriano, Marco Guzzi, Antonio Mariano

摘要:

我们描述了一个超对称模型(USSM-A)的结构和主要唯象学特征,该模型是用自底向上的方法建立的,包含一个反常的阿贝尔规范对称性。该模型支持规范的轴子在其频谱,并提供了一个推广的全球(超对称)Peccei-Quinn建设。完成模拟的中性伴子遗迹密度。CAST和WMAP的边界,结合暗物质模拟,对轴子和规范场之间的相互作用的尺度提供了重要的约束。

英文摘要:

We illustrate the structure and the main phenomenological features of a supersymmetric model (the USSM-A) built following a bottom-up approach and containing an anomalous abelian gauge symmetry. This model supports a gauged axion in its spectrum and provides a generalization of the global (supersymmetric) Peccei-Quinn construction. Complete simulations of the neutralino relic density are performed. Bounds from CAST and WMAP, combined with dark matter simulations, provide significant constraints on the scale of the interactions between the axion and the gauge fields.
