利用太阳CEνNS测量测试轻重矢量介质中介子,通过联合分析核 recoil 数据提取中微子通量归一化和弱混合角信息,推导非标准中微子相互作用约束。

摘要:

最近在暗物质直接探测实验中观测到来自太阳⁸B中微子的相干弹性中微子-核散射,标志着中微子雾时代开始,突显了这些实验作为精密中微子观测站的广阔潜力。XENONnT、PandaX-4T和LUX-ZEPLIN实验的最新测量提供了测试标准模型预测和探测其之外物理的新机会,与专门的中微子设施互补。我们对这三个设施的核 recoil 数据进行了联合分析,以提取关于太阳⁸B中微子通量归一化和低动量转移下的弱混合角的信息。我们进一步研究了新矢量相互作用对太阳中微子事件率的影响,推导出对非标准中微子相互作用和具有轻矢量介质场景的约束。我们的结果表明,暗物质探测器正在迅速成为地面中微子实验的补充,在探测中微子相互作用方面已经设定了对轻和重矢量介质的竞争性限制。

英文摘要:

The recent observation of coherent elastic neutrino-nucleus scattering from solar $^8$B neutrinos in dark matter direct detection experiments has inaugurated the \emph{neutrino fog} era, highlighting the extended potential of these experiments as precision neutrino observatories. Recent measurements by the XENONnT, PandaX-4T, and LUX-ZEPLIN experiments provide new opportunities to test Standard Model predictions and to probe physics beyond it, in complementarity with dedicated neutrino facilities. We perform a combined analysis of nuclear recoil data from these three facilities to extract information on the solar $^8$B neutrino flux normalization and on the weak mixing angle at low-momentum transfer. We further investigate the impact of new vector interactions on the solar neutrino event rate, deriving constraints on nonstandard neutrino interactions and on scenarios with light vector mediators. Our results demonstrate that dark matter detectors are rapidly becoming complementary to terrestrial neutrino experiments in probing neutrino interactions, and already set competitive bounds on both light and heavy vector mediators.
