我们报告了XENON1T暗物质实验中弱相互作用大质量粒子（wimp）的非弹性散射的研究结果。$^{129}$Xe的散射是WIMP非弹性相互作用最敏感的探针，在核反冲同时检测到39.6 keV的退激光子。使用0.89吨年的暴露，我们没有发现显著性大于2$\sigma$的非弹性WIMP散射的证据。采用谱似然比分析方法确定了wimp -原子核相互作用截面的上限。我们排除了重于100 GeV/c${}^2$的wimp的新参数空间，在90%置信水平下，对于130 GeV/c${}^2$ wimp，最强上限为$3.3 \乘以10^{-39}$ cm${}^2$。
We report the results of a search for the inelastic scattering of weakly interacting massive particles (WIMPs) in the XENON1T dark matter experiment. Scattering off $^{129}$Xe is the most sensitive probe of inelastic WIMP interactions, with a signature of a 39.6 keV de-excitation photon detected simultaneously with the nuclear recoil. Using an exposure of 0.89 tonne-years, we find no evidence of inelastic WIMP scattering with a significance of more than 2$\sigma$. A profile-likelihood ratio analysis is used to set upper limits on the cross-section of WIMP-nucleus interactions. We exclude new parameter space for WIMPs heavier than 100 GeV/c${}^2$, with the strongest upper limit of $3.3 \times 10^{-39}$ cm${}^2$ for 130 GeV/c${}^2$ WIMPs at 90\% confidence level.
