AI总结:

摘要:

我们研究了拟建于欧洲散裂源(ESS)的一批未来探测器通过相干弹性中微子-核散射探测中微子微电荷的潜力。具体而言,我们聚焦于与正在研发的、将在ESS运行的探测器特性相似的设备,涵盖基于碘化铯、锗以及稀有气体的探测技术。在我们考虑的条件下,研究表明:相较于CsI和氙这类稀有气体,核靶质量更轻的Ge探测器在约束中微子微电荷方面效率更高,对对角中微子微电荷的灵敏度可达约10^-9 e,对跃迁中微子微电荷的灵敏度约为10^-8 e。此外,我们还研究了在CsI探测器中纳入电子散射过程的效应,其对对角微电荷的预期灵敏度可达约10^-10 e。

英文摘要:

We study the potential of a set of future detectors, proposed to be located at the European Spallation Source (ESS), to probe neutrino millicharges through coherent elastic neutrino-nucleus scattering. In particular, we focus on detectors with similar characteristics as those that are under development for operation at the ESS, including detection technologies based on cesium iodine, germanium, and noble gases. Under the considered conditions, we show that the Ge detector, with a lighter nuclear target mass with respect to CsI and to a noble gas like Xe, is more efficient to constrain neutrino millicharges, reaching a sensitivity of $\sim 10^{-9}e$ for diagonal neutrino millicharges, and $\sim 10^{-8}e$ for the transition ones. In addition, we study the effects of including electron scattering processes for the CsI detector, achieving an expected sensitivity of $\sim 10^{-10} e$ for the diagonal millicharges.
