本研究利用核反冲与太阳中微子数据，结合LUX-ZEPLIN候选事件，解析NMSSM中Singlino-Higgsino暗物质的组成，通过区分基态类型和跃迁机制，为暗物质性质探测提供新途径。
AI 中文摘要
核反冲测量暗物质（DM）在核子上的散射，但通常无法揭示晕中暗物质的本质。暗物质基态与激发态的互换可以在保持非弹性反冲谱不变的同时，将基态湮灭改变几个数量级。太阳中微子随后可以提供核反冲无法解决的信息。受高能LUX-ZEPLIN候选事件的启发，我们研究了一种利用核反冲和太阳中微子解析次最小超对称标准模型（NMSSM）中Singlino-Higgsino暗物质组成的可能途径。我们的分析识别出与太阳观测相容的Singlino基态和具有弱非弹性跃迁的Higgsino基态，而Higgsino对非弹性LZ拟合则预测过量的太阳信号。一种弹性Higgsino散射替代方案可以通过关闭非弹性跃迁来抑制太阳俘获。因此，反冲谱、太阳演化和靶标互补性可以探测Singlino-Higgsino暗物质组成的不同方面，剩余简并性由湮灭、晕和探测器假设决定。
英文摘要
A nuclear recoil measures dark matter (DM) scattering on nucleons, but usually cannot reveal the nature of the halo DM. An interchange of the ground and excited states of the DM can preserve an inelastic recoil spectrum while changing ground-state annihilation by several orders of magnitude. Solar neutrinos can then provide information that nuclear recoils leave unresolved. Motivated by the high-energy LUX-ZEPLIN candidate, we investigate a possible way to resolve the composition of singlino-Higgsino DM in the next-to-minimal supersymmetric standard model (NMSSM) by using nuclear recoils and solar neutrinos. Our analysis identifies solar-compatible singlino ground states and Higgsino ground states with weak inelastic transitions, whereas Higgsino-pair inelastic LZ fits predict excessive solar signals. An elastic Higgsino scattering alternative can suppress solar capture by closing the inelastic transition. Recoil spectra, solar evolution and target complementarity can therefore probe distinct aspects of the singlino-Higgsino DM composition, with residual degeneracies set by annihilation, halo and detector assumptions.
