在NMSSM的允许参数空间中，Light Singlino样中性裔有望成为DM的有前途的候选者。 DM歼灭过程通过该模型自然的光希格斯玻色子进行。识别允许的参数空间区域，包括各种约束，在LHC上探索了这种光DM候选者和Higgs玻色子的检测前景，其高光度选项。 Light Higgs玻色子和DM候选者，最轻的单利尼基中性裔是通过SM Higgs的产量及其随后的衰减在LHC上间接生产的。喷气子结构技术用于标记增强的希格斯。发现可以在LHC上发现具有合理的信号意义（$ \ sim5σ$）的与低质量DM解决方案相兼容的大量Higgs Bosons和Neutralino群体范围，其中具有合理的信号意义（$ \ sim5σ$），并具有质量$ \ sqrt的中心$ \ sqrt {s}} = 14 $ tev tev and tev and tev and Integrated Luminusisy $ \ cal ccal l} = 300〜fb^{ - 1} $和3000 $ \ rm fb^{ - 1} $。
The light singlino-like neutralino is expected to be a promising candidate for DM in the allowed parameter space of the NMSSM. The DM annihilation process takes place via the light Higgs bosons which are natural in this model. Identifying the allowed region of parameter space including various constraints, the detection prospect of such light DM candidate and Higgs bosons are explored at the LHC with its high luminosity options. Light Higgs bosons and the DM candidate, the lightest singlino-like neutralino are indirectly produced at the LHC via the SM Higgs production and its subsequent decays. Jet substructure techniques are used to tag boosted Higgs. It is found that the favourable range of masses of Higgs bosons and neutralino, compatible with a low mass DM solution, can be discovered with a reasonable signal significance ($\sim 5 σ$) at the LHC, with the center of mass energy $\sqrt{s}=14$ TeV and integrated luminosity options $\rm{\cal L}=300~fb^{-1}$ and 3000 $\rm fb^{-1}$.
