暗物质探测中超对称性破缺的规范调解现象

Phenomenological Aspects of Gauge Mediation with Sequestered Supersymmetry Breaking in light of Dark Matter Detection

Motoi Endo, Satoshi Shirai, Kazuya Yonekura

摘要:

在最近的一项工作中,提出了一个具有隔离超对称性破缺的规范介导模型。在这个模型中,引力子的质量是O(100)GeV,而不会引起中性流的味道变化问题。与传统的规范介导相反,引力伴子不是最轻的超对称粒子,中性伴子是暗物质的候选者。在本文中,我们调查的唯象方面,这个模型和讨论的可能性直接检测的暗物质。特别是,我们专注于轻中性伴子的情况下,发现光希格斯诺场景,如焦点是有趣的,考虑到最近的CDMS结果。

英文摘要:

In a recent work, a model of gauge mediation with sequestered supersymmetry (SUSY) breaking was proposed. In this model, the mass of the gravitino is O(100) GeV without causing the flavor-changing neutral-current problem. In contrast to traditional gauge mediation, the gravitino is not the lightest SUSY particle and the neutralino is the candidate of the dark matter. In this paper, we investigate phenomenological aspects of this model and discuss the possibility of the direct detection of the dark matter. In particular, we focus on the light neutralino case and find that the light-Higgsino scenario such as the focus point is interesting, taking account of the recent CDMS result.
