论文摘要
据报道，反应堆中，对低阈值闪烁的氩气泡室的敏感性。也就是说，研究了轻标量介体，无菌中微子振荡，违反单位性和非标准相互作用。结果表明，该检测器可以比最近的连贯测量设置的当前限制设置更强的限制。考虑到最佳方案，一个100千克检测器位于2000 mw $ _ {th} $反应堆中，无菌中微子搜索将涵盖反应堆抗中性异常拟合的大部分空间参数。违反单位性的研究可能会对$α_{11} $的限制设置比当前的振荡实验更严格。背景非常低的低阈值氩探测器有可能在不同情况下探索新物理学并设定竞争性限制。
The sensitivity to New Physics of a low threshold scintillating argon bubble chamber measuring coherent elastic neutrino-nucleus scattering in reactors is reported. Namely, light scalar mediators, sterile neutrino oscillations, unitarity violation, and non-standard interactions are studied. The results indicate that this detector could be able to set stronger constraints than current limits set by the recent COHERENT measurements. Considering the best scenario, a 100 kg detector located 30 m from a 2000 MW$_{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 $α_{11}$ 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.
