论文摘要
我们使用对应于总暴露于0.63〜tonne $ \ cdot $年的数据集,对轴向矢量和伪量表中介导的wimp-nucleus相互作用介绍了限制。未观察到明显的信号过量,并且迄今为止最严格的上限在旋转依赖性的WIMP-NEUTRON散射横截面上设置为90 \%置信度,最小WIMP-NEUTRON散射横截面为5.8 $ \ times 10^{ - 42} $ \ si {$ \ si {\ si {\ si {\ cm^{2}} 40〜 \ si {\ gev/} $ c^2 $。还得出了轴向矢量和伪量表简化模型的排除限制。
We present the constraints on the axial-vector and pseudo-scalar mediated WIMP-nucleus interactions from the PandaX-4T experiment, using the data set corresponding to a total exposure of 0.63~tonne$\cdot$year. No significant signal excess is observed, and the most stringent upper limits to date on the spin-dependent WIMP-neutron scattering cross section are set at 90\% confidence level with the minimum WIMP-neutron scattering cross section of 5.8$\times 10^{-42}$\si{\cm^{2}} for WIMP mass of 40~\si{\GeV/}$c^2$. Exclusion limits on the axial-vector and pseudo-scalar simplified models are also derived.
