论文摘要

大型的地下氙(LUX)暗物质搜索是一个250公斤活性的质量双相投影室,该室通过检测到XENON目标上的粒子的光和电离信号操作。 2015年12月,Lux报告至少90%的C.L.在第一次科学运行中,基于1.4e4 kg*day暴露的旋转wimp-nucleon弹性散射横截面上的6e-46 cm^2。实验之间的张力和没有确定的阳性检测表明,在标准旋转独立于/旋转依赖性范式之外寻找wimps是谨慎的。最近的理论工作已经确定了14个独立有效田间理论(EFT)操作员的完整基础,以描述Wimp-Nucleon相互作用。除了自旋非依赖性和自旋依赖性核反应外,这些操作员还可以产生新的响应,例如角摩肌依赖性和自旋轨道耦合。在这里,我们报告了搜索所有14个EFT耦合的搜索,其中包括Lux首次科学运行中的数据。将限制放在每个耦合上,作为WIMP质量的函数。

The Large Underground Xenon (LUX) dark matter search was a 250-kg active mass dual-phase time projection chamber that operated by detecting light and ionization signals from particles incident on a xenon target. In December 2015, LUX reported a minimum 90% upper C.L. of 6e-46 cm^2 on the spin-independent WIMP-nucleon elastic scattering cross section based on a 1.4e4 kg*day exposure in its first science run. Tension between experiments and the absence of a definitive positive detection suggest it would be prudent to search for WIMPs outside the standard spin-independent/spin-dependent paradigm. Recent theoretical work has identified a complete basis of 14 independent effective field theory (EFT) operators to describe WIMP-nucleon interactions. In addition to spin-independent and spin-dependent nuclear responses, these operators can produce novel responses such as angular-momentum-dependent and spin-orbit couplings. Here we report on a search for all 14 of these EFT couplings with data from LUX's first science run. Limits are placed on each coupling as a function of WIMP mass.
