标题： Direct Detection of Neutralino Dark Matter and the Anomalous Dipole Moment of the Muon

摘要： 我们比较了在引力介导超对称破缺模型中中性微子-质子散射截面的自旋无关贡献$\sig$以及缪子的异常磁偶极矩$a_\mu = (g_\mu-2)/2$的预测。 我们几乎总是发现这两个可测量量之间存在正相关，即具有较大$a_\mu$的情景也往往具有较大的$\sig$，但不同模型之间的详细预测差异很大。 特别是，我们发现对于在大统一尺度具有通用软破缺质量的流行 mSUGRA 情景，目前测量$a_\mu$看起来更有希望。 另一方面，如果大统一尺度的标量软破缺质量从 SO(10) D 项获得显著贡献，通常会发现具有较大$\sig$但$a_\mu$低于目前预期灵敏度的情景。 一个具有大统一尺度非通用标量谱的弦理论启发模型介于这两种情况之间。 显示英文摘要

摘要： We compare predictions for the spin-independent contribution to the neutralino-proton scattering cross section $\sig$ and for the anomalous magnetic dipole moment of the muon, $a_\mu = (g_\mu-2)/2$, in models with gravity-mediated supersymmetry breaking. We nearly always find a positive correlation between these two measurables, i.e. scenarios with larger $a_\mu$ also tend to have larger $\sig$, but the detailed prediction differs greatly between models. In particular, we find that for the popular mSUGRA scenario with universal soft breaking masses at the scale of Grand Unification, measurements of $a_\mu$ currently seem more promising. On the other hand, if scalar soft breaking masses at the GUT scale receive sizable contributions from SO(10) D-terms, one often finds scenarios with large $\sig$ but $a_\mu$ below the currently foreseen sensitivity. A string-inspired model with non-universal scalar spectrum at the GUT scale falls between these two cases.
