用Skipper-CCD进行反应堆中微子实验的物理势:寻找光介质的新物理
The physics potential of a reactor neutrino experiment with Skipper-CCDs: Searching for new physics with light mediators
摘要:
我们探讨了最近提出的vIOLETA实验的新物理的灵敏度:一个10公斤的船长电荷耦合器件探测器部署在12米远的商业核反应堆堆芯。我们调查两大类模型,受益于这些探测器的非常低的能量反冲阈值,即中微子磁矩和光介质耦合到中微子和夸克或电子。我们发现,这种实验装置对光,弱耦合新物理非常敏感,特别是它可以探测在XENON 1 T中观察到的事件过量的潜在解释。我们还提供了一个详细的研究的灵敏度的实验装置的假设和中微子通量系统的不确定性的依赖关系。
英文摘要:
We explore the sensitivity to new physics of the recently proposed vIOLETA experiment: a 10 kg Skipper Charged Coupled Device detector deployed 12 meters away from a commercial nuclear reactor core. We investigate two broad classes of models which benefit from the very low energy recoil threshold of these detectors, namely neutrino magnetic moments and light mediators coupled to neutrinos and quarks or electrons. We find that this experimental setup is very sensitive to light, weakly coupled new physics, and in particular that it could probe potential explanations of the event excess observed in XENON1T. We also provide a detailed study on the dependence of the sensitivity on the experimental setup assumptions and on the neutrino flux systematic uncertainties.
