没有已知的原因表明暗物质与标准模型的相互作用应该以相同的方式耦合到中子和质子。这种同位旋破坏可能会产生很大的后果，修改现有和未来的直接检测实验约束的灵敏度的数量级。以往的研究工作主要集中在零动量极限上，当把分析扩展到非相对论有效场论基础（NREFT）时，零动量极限有其局限性。在本文中，我们详细研究了同位旋破坏的方式，特别注意的实验装置的液体惰性气体探测器。我们分析了两个有效的标准模型规范不变模型作为有趣的案例研究，以及更多的模型无关的NREFT运营商。这项工作证明了靶核氙和氩之间的高度互补性。最值得注意的是，我们表明，标准模型规范不变的制定标准的自旋相关的相互作用往往会产生相当大的响应，从氩，零自旋的目标核。这项工作的目的是作为一个更新和有用的参考模型建设者和实验。
There is no known reason that dark matter interactions with the Standard Model should couple to neutrons and protons in the same way. This isospin violation can have large consequences, modifying the sensitivity of existing and future direct detection experimental constraints by orders of magnitude. Previous works in the literature have focused on the zero-momentum limit which has its limitations when extending the analysis to the Non-Relativistic Effective Field Theory basis (NREFT). In this paper, we study isospin violation in a detailed manner, paying specific attention to the experimental setups of liquid noble detectors. We analyse two effective Standard Model gauge invariant models as interesting case studies as well as the more model-independent NREFT operators. This work demonstrates the high degree of complementarity between the target nuclei xenon and argon. Most notably, we show that the Standard Model gauge-invariant formulation of the standard spin-dependent interaction often generates a sizeable response from argon, a target nuclei with zero spin. This work is meant as an update and a useful reference to model builders and experimentalists.
