论文摘要

随着暗物质直接检测实验的快速发展,经济超对称理论中流行的Bino主导的暗物质的吸引力正在消失。作为替代方案,总体上,以单利主导的暗物质为单位的暗物质是近代的超对称标准模型(NMSSM)。 This scenario has the following distinct characteristics: free from the tadpole problem and the domain-wall problem of the NMSSM with a $Z_3$-symmetry, predicting more stable vacuum states than the $Z_3$-NMSSM, capable of forming an economical secluded dark matter sector to yield the dark matter experimental results naturally, and readily weaken the restrictions from the LHC search for SUSY.因此,它可以在广泛的参数空间中解释MUON G-2异常,该空间与各种实验结果一致,同时自然打破了电子对称性。在这项研究中,我们详细介绍了场景如何与实验相吻合,例如在LHC上的Susy搜索,通过LZ实验进行的暗物质搜索以及改进的MUON G-2测量值。我们提供了一般NMSS固有的物理学的简单清晰图片。

With the rapid progress of dark matter direct detection experiments, the attractiveness of the popular bino-dominated dark matter in economical supersymmetric theories is fading. As an alternative, the singlino-dominated dark matter in general Next-to-Minimal Supersymmetric Standard Model (NMSSM) is paying due attention. This scenario has the following distinct characteristics: free from the tadpole problem and the domain-wall problem of the NMSSM with a $Z_3$-symmetry, predicting more stable vacuum states than the $Z_3$-NMSSM, capable of forming an economical secluded dark matter sector to yield the dark matter experimental results naturally, and readily weaken the restrictions from the LHC search for SUSY. Consequently, it can explain the muon g-2 anomaly in broad parameter space that agrees with various experimental results while simultaneously breaking the electroweak symmetry naturally. In this study, we show in detail how the scenario coincides with the experiments, such as the SUSY search at the LHC, the dark matter search by the LZ experiment, and the improved measurement of the muon g-2. We provide a simple and clear picture of the physics inherent in the general NMSSM.
