在大型强子对撞机上的超对称性搜索以及126 GeV的希格斯玻色子表明，超粒子，特别是方子和胶子，并不像我们预期的那么轻。研究不依赖于有色超粒子的超对称搜索是很重要的。作为一个线索的调查，我们专注于μ子g-2异常，这可以解释的超对称贡献，如果一些中性伴子，charginos，slepton是为了100 GeV的光。我们提出了μ子-（g-2）-动机MSSM作为基准模型，其中的squarks是去耦的，但对应于μ子g-2的超粒子是轻到足以解释的异常。我们还解释了LHC超对称性搜索的最新结果，并获得了对模型的实验约束。我们发现，对charginos和neutralinos的直接生产的搜索工作非常好的情况下，但几个地区不仅仍然没有发现，但甚至发现在大型强子对撞机搜索具有挑战性。可以肯定的是，为了发挥LHC的潜力，应该制定攻击这些区域的策略。
SUSY searches at the LHC as well as the 126 GeV Higgs boson indicate that superparticles, especially squarks and gluinos, are not so light as we expected. It is important to investigate SUSY searches which do not rely on the colored superparticles. As a clue for the investigation, we focus on the muon g-2 anomaly, which can be explained by the SUSY contributions if some of neutralinos, charginos, and sleptons are as light as of order 100 GeV. We propose the muon-(g-2)-motivated MSSM as a benchmark model, where squarks are decoupled but the superparticles corresponding to the muon g-2 are light enough to explain the anomaly. We also interpret the up-to-date results of LHC SUSY searches, and obtain experimental constraints on the model. We show searches for direct production of charginos and neutralinos work very well against the scenario, but several regions are not only remain uncovered but even found challenging to be searched for at the LHC. It is ascertained that, in order to draw out latent potential of the LHC, strategies to attack these regions should be developed.
