本文报道了用低阈值膨胀氩泡室测量反应堆中中微子-核相干弹性散射对新物理的灵敏度。即，光标量介质，不育中微子振荡，幺正性破坏，和非标准相互作用的研究。结果表明，该检测器可以设置更强的约束比目前的限制设置最近的相干测量。考虑到最好的情况，一个100公斤的探测器位于距离2000兆瓦的反应堆30米处，无菌中微子搜索将覆盖反应堆反中微子异常拟合所允许的大部分空间参数。幺正性破坏研究可以对$\alpha_{11}$设置比当前振荡实验更严格的约束。具有非常低背景的低阈值氩探测器具有在不同场景中探索新物理学并设置竞争约束的潜力。
The sensitivity to New Physics of a low threshold scintillating argon bubble chamber measuring coherent elastic neutrino-nucleus scattering in reactors is reported. Namely, light scalar mediators, sterile neutrino oscillations, unitarity violation, and non-standard interactions are studied. The results indicate that this detector could be able to set stronger constraints than current limits set by the recent COHERENT measurements. Considering the best scenario, a 100 kg detector located 30 m from a 2000 MW$_{th}$ reactor, a sterile neutrino search would cover most of the space parameter allowed from the reactor anti-neutrino anomaly fit. Unitarity violation studies could set constraints on $\alpha_{11}$ more stringent than the current oscillation experiments fit. A low threshold argon detector with very low backgrounds has the potential to explore New Physics in different scenarios and set competitive constraints.
