论文摘要
我们研究了一种可能性解释标准模型预测和在中性中性不稳定的非正统SUSY场景中观察磁矩异常磁矩的观察值之间的差异。首先，我们在MSSM中审查MUON G-2计算，并与最新的实验约束面对面。我们发现，下一代直接检测DM实验与当前的LHC结果结合使用，最终将测试可以解释MSSM中$（g-2）_μ$异常的参数区域。接下来，我们研究了违反和仪介导的SUSY破裂的场景，具有不稳定的中性元。这些模型没有提供可行的DM候选者，这使他们可以逃避DM约束。我们发现，在带有Slepton NLSP的RPV和GMSB中，LHC约束较弱，并且很大的参数空间可以解释观察到的异常和逃避实验限制。
We investigate a possibility to explain the discrepancy between the Standard Model predictions and the observed value of the anomalous magnetic moment of the muon within unorthodox SUSY scenarios in which neutralinos are unstable. We start by reviewing the muon g-2 calculations in the MSSM and confront it with the most up-to-date experimental constraints. We find out that the next generation of direct detection DM experiments combined with the current LHC results will ultimately test the parameter region that can explain the $(g-2)_μ$ anomaly in the MSSM. Next, we study R-parity violating and gauge-mediated SUSY-breaking scenarios with unstable neutralinos. These models do not provide a viable DM candidate, which allows them to evade the DM constraints. We find that in RPV and GMSB with slepton NLSP the LHC constraints are weaker, and a large region of parameter space can explain the observed anomaly and evade experimental limits.
