本文研究类Higgsino暗物质非弹性散射的直接探测，通过壳上重整化和单圈电弱修正计算散射截面，发现非弹性分量可超过弹性分量，增强探测率。
AI 中文摘要
通过非弹性散射过程对类Higgsino暗物质（DM）的直接探测（DD），在弹性散射之外，当中性Higgsino对之间的质量劈裂极小时，可能提供一条有前景的途径。通过在MSSM中对中性和带电Higgsino采用壳上重整化，质量劈裂可以进一步减小。此外，已考虑中性伴子-希格斯相互作用三点顶角的所有单圈电弱（EW）修正，而弹性与非弹性DM-核子散射截面主要通过希格斯交换进行计算。随后，还计算了最新LUX-ZEPLIN（LZ）DD实验中预期的散射事件数。我们的结果突出了几种非弹性分量可能超过相应弹性分量的情景，从而导致增强的直接探测散射率。
英文摘要
The direct detection (DD) of Higgsino-like dark matter (DM) through inelastic scattering processes may provide a promising avenue, along with the elastic scattering, when the mass splitting between the neutral Higgsino pairs is extremely tiny. The mass splitting can be reduced further by adopting the on-shell renormalization for the neutral and charged Higgsinos in the MSSM. Moreover, all the one-loop electroweak (EW) corrections to the three-point vertices for the neutralino(s)-Higgs interactions have been considered, while both elastic and inelastic DM-nucleon scattering cross-sections have been calculated primarily through Higgs exchange. Subsequently, the expected number of scattering events in the latest LUX-ZEPLIN (LZ) DD experiment are also computed. Our results highlight a few scenarios in which the inelastic component may exceed the corresponding elastic component, leading to enhanced direct detection scattering rates.
