论文摘要

我们根据CDEX-1B和CDEX-10阶段的数据，使用了两种有效的现场理论（CDEX）进行的两种有效现场理论进行的弱相互作用的巨大颗粒（WIMP）搜索结果。在非依赖主义有效的现场理论方法中，使用时间集成和年度调制分析为WIMP-Nucleon有效运算符的耦合设定了新的限制，以90％的置信度（C.L.），并改善了低$M_χ$区域的当前界限。在手性有效现场理论方法中，使用CDEX-10的数据将WIMP-PION耦合的上限设置为90％C.L.我们首次将限制扩展到$M_χ<$ 6 GEV/$ C^2 $ region。

We present weakly interacting massive particles (WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment (CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level (C.L.) and improve over the current bounds in the low $m_χ$ region. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the $m_χ<$ 6 GeV/$c^2$ region.
