鉴于最新的大型强子对撞机和暗物质直接和间接探测实验，我们重新审视了标准模型场景的最小超对称扩展，其中轻中性伴子作为暗物质候选者。我们表明，一个非常轻的中性伴子（类似于10 GeV）和标量底夸克接近质量的情况下，可以满足所有可用的限制LEP，Tevatron，LHC，风味和低能量的实验，并提供解决方案，与大部分的暗物质直接探测实验，特别是与最近的CDMS结果。
We revisit minimal supersymmetric extension of the Standard Model scenarios with light neutralino as a dark matter candidate in view of the latest LHC and dark matter direct and indirect detection experiments. We show that scenarios with a very light neutralino (similar to 10 GeV) and a scalar bottom quark close in mass can satisfy all the available constraints from LEP, Tevatron, LHC, flavor and low energy experiments and provide solutions in agreement with the bulk of dark matter direct detection experiments, and in particular with the recent CDMS results.
