In this paper we perform for the first time an in-depth analysis of the spectra in the phenomenological supersymmetric Standard Model that simultaneously offer an explanation for the $(g-2)_{\mu}$ discrepancy $\Delta a_{\mu}$, result in the right dark-matter relic density $\Omega_{\rm DM} h^2$ and are minimally fine-tuned. The resulting spectra may be obtained from [1]. To discuss the experimental exclusion potential for our models, we analyse the resulting LHC phenomenology as well as the sensitivity of dark-matter direct detection experiments to these spectra. We find that the latter type of experiments with sensitivity to the spin-dependent dark-matter\,--\,nucleon scattering cross section $\sigma_{\rm SD,p}$ will probe all of our found solutions.

pMSSM 中的暗物质、微调和 (g-2)_{\mu}

在本文中,我们首次对现象学超对称标准模型中的光谱进行了深入分析,同时解释了 $(g-2)_{\mu}$ 差异 $\Delta a_{\mu }$,导致正确的暗物质遗物密度 $\Omega_{\rm DM} h^2$ 并进行了最低限度的微调。所得光谱可以从[1]获得。为了讨论我们模型的实验排除潜力,我们分析了由此产生的 LHC 现象学以及暗物质直接检测实验对这些光谱的敏感性。我们发现后一种对自旋相关暗物质\,--\, 核子散射截面 $\sigma_{\rm SD,p}$ 敏感的实验将探测我们找到的所有解决方案。
