普适和非普适Gaugino质量模型中的SUSY暗物质

SUSY Dark Matter in Universal and Nonuniversal Gaugino Mass Models

D. P. Roy

摘要:

我们回顾了超对称暗物质的现象学在各种版本的MSSM,具有普遍的和非普遍的高根质量在大统一尺度。我们从宇宙的情况(CMSSM)开始,宇宙相容的暗物质遗迹密度只在参数空间的一些狭窄区域内实现,涉及一些微调。此外,这些区域中的大多数受到对撞机和直接暗物质探测实验的限制。然后,我们考虑一些简单的和预测的非普适的gaugino质量模型,基于SU(5)大统一理论。这些模型提供了可行的超对称暗物质候选者,这是兼容的宇宙暗物质遗迹密度和上述实验的限制。它们可以在现在和未来的对撞机和暗物质搜索实验中探测。最后,我们考虑了由反常介导的超对称性破缺引起的非普适高更质量模型。在这种情况下,宇宙相容的暗物质遗迹密度需要几TeV的暗物质质量,这使得它超出了对撞机和直接暗物质探测实验的范围。但是,它对一些间接的暗物质探测实验有有趣的预测。

英文摘要:

We review the phenomenology of SUSY dark matter in various versions of MSSM, with universal and nonuniversal gaugino masses at the GUT scale. We start with the universal case (CMSSM), where the cosmologically compatible dark matter relic density is achieved only over some narrow regions of parameter space, involving some fine-tuning. Moreover, most of these regions are seriously challenged by the constraints from collider and direct dark matter detection experiments. Then we consider some simple and predictive nonuniversal gaugino mass models, based on SU(5) GUT. Several of these models offer viable SUSY dark matter candidates, which are compatible with the cosmic dark matter relic density and the above mentioned experimental constraints. They can be probed at the present and future collider and dark matter search experiments. Finally, we consider the nonuniversal gaugino mass model arising from anomaly mediated SUSY breaking. In this case the cosmologically compatible dark matter relic density requires dark matter mass of a few TeV, which puts it beyond the scope of collider and direct dark matter detection experiments. However, it has interesting predictions for some indirect dark matter detection experiments.
