本文报道了利用LUX数据进行非相对论有效场论（EFT） WIMP搜索分析的结果。我们在之前LUX分析的基础上，将搜索窗口扩展到包括高达180kev / nr的核反冲能量，这需要对数据质量标准和背景模型进行重新评估。为了使用无箱化剖面似然统计框架，需要开发新的分析技术来解释高能背景。有一个3。使用2014年至2016年收集的数据，我们发现我们的数据与背景期望相兼容，并为非相对论性EFT WIMP-核子耦合设置了90%的c.l排除限制，改进了之前的LUX结果，并提供了使用f中子的EFT WIMP相互作用的约束；质子相互作用基础。此外，我们报告了非弹性EFT wimp -等标量反冲的排除限制，这些限制在几个相互作用算子中具有竞争力和世界领先地位。
We report here the results of a nonrelativistic effective field theory (EFT) WIMP search analysis using LUX data. We build upon previous LUX analyses by extending the search window to include nuclear recoil energies up to ∼ 180 keV nr , requiring a reassessment of data quality criteria and background models. In order to use an unbinned profile likelihood statistical framework, the development of new analysis techniques to account for higher-energy backgrounds was required. With a 3 . 14 × 10 4 kg · day exposure using data collected between 2014 and 2016, we find our data is compatible with the background expectation and set 90% C.L. exclusion limits on nonrelativistic EFT WIMP-nucleon couplings, improving upon previous LUX results and providing constraints on a EFT WIMP interactions using the f neutron ; proton g interaction basis. Additionally, we report exclusion limits on inelastic EFT WIMP-isoscalar recoils that are competitive and world-leading for several interaction operators.
