论文摘要
到目前为止，暗物质的特性还不为人所知。但是，可以通过使用标准模型中的各种对称性来实现候选暗物质候选者的模型分类。费米金暗物质已经进行了极大的研究，其中一个受欢迎的候选人是最小的超对称标准模型中的中性诺，这是费米尼 - 玻色子对称性和保留R-Parity所要求的。尚未充分研究玻色粒暗物质，尤其是Sub-Gev质量的暗物质方案。在本文中，我们考虑了自旋依赖性（SD）对标量和矢量暗物质的影响，它们是由伪量表和轴向矢量介导的，并评估对暗物质电子散射横截面的影响。我们列出了深色电子SD散射的所有相互作用和外形，并使用Xenon10/100/1t实验数据来得出SD横截面的排除极限。我们发现，由于$ p $ - 波散射，标量和矢量暗物质的SD散射可能比自旋非依赖（SI）散射强三个数量级。
The property of dark matter is unknown so far. However, a model-independent classification of dark matter candidates can be achieved by using various symmetries, as done in the Standard Model. Fermionic dark matter has been researched extremely, one favored candidate is the neutralino in the Minimal Supersymmetric Standard Model, which are required by fermion-boson symmetry and preservation of R-parity. Bosonic dark matter has not been studied sufficiently, especially the scenario of dark matter with mass of sub-GeV. In this paper, we consider the effect of spin-dependent (SD) on scalar and vector dark matter, which are mediated by pseudo-scalar and axial-vector, and evaluate effect on the dark matter-electron scattering cross section. We list all the interaction and form factor of dark matter-electron SD scattering, and use XENON10/100/1T experiment data to derive the exclude limit of SD cross section. We find that the SD scattering of scalar and vector dark matter can be three orders of magnitude stronger than spin-independent (SI) scattering, due to the $p$-wave scattering.
