Title: 暗物质在具有非通用希格斯质量的MSSM中的直接探测

Abstract: We calculate dark matter scattering rates in the minimal supersymmetric extension of the Standard Model (MSSM), allowing the soft supersymmetry-breaking masses of the Higgs multiplets, m_{1,2}, to be non-universal (NUHM). Compared with the constrained MSSM (CMSSM) in which m_{1,2} are required to be equal to the soft supersymmetry-breaking masses m_0 of the squark and slepton masses, we find that the elastic scattering cross sections may be up to two orders of magnitude larger than values in the CMSSM for similar LSP masses. We find the following preferred ranges for the spin-independent cross section: 10^{-6} pb \ga \sigma_{SI} \ga 10^{-10} pb, and for the spin-dependent cross section: 10^{-3} pb \ga \sigma_{SD}, with the lower bound on \sigma_{SI} dependent on using the putative constraint from the muon anomalous magnetic moment. We stress the importance of incorporating accelerator and dark matter constraints in restricting the NUHM parameter space, and also of requiring that no undesirable vacuum appear below the GUT scale. In particular, values of the spin-independent cross section another order of magnitude larger would appear to be allowed, for small \tan \beta, if the GUT vacuum stability requirement were relaxed, and much lower cross-section values would be permitted if the muon anomalous magnetic moment constraint were dropped.

Abstract: 我们在标准模型的最小超对称扩展（MSSM）中计算暗物质散射率，允许希格斯多重态的软超对称破缺质量 m_{1,2}不是统一的（NUHM）。 与受约束的MSSM（CMSSM）相比，在CMSSM中要求 m_{1,2}与squark和slepton质量的软超对称破缺质量 m_0 相等，我们发现对于类似的LSP质量，弹性散射截面可能比CMSSM中的值大两个数量级。 我们找到自旋无关截面的以下优先范围：10^{-6} pb \ga \sigma _{国际单位制} \ga 10^{-10} pb，以及自旋相关截面的：10^{-3} pb \ga \sigma _{SD}，其中对\sigma _{国际单位制}的下限依赖于使用来自μ子反常磁矩的假设约束。 我们强调在限制NUHM参数空间时，纳入加速器和暗物质约束的重要性，同时也强调在GUT尺度以下不得出现不期望的真空状态的要求。 特别是，如果放松GUT真空稳定性要求，对于较小的\tan \beta ，自旋无关截面的值可能会大一个数量级，如果放弃μ子异常磁矩约束，将允许更低的截面值。
