摘要:

在中微子振荡数据中观察到的几个异常现象可以用一个假设的第四个中微子来解释,该中微子与三个标准中微子之间的质量平方差为几个eV ^[2]。我们表明,这一假设可以用PBq(十千居里尺度)144 Ce或106 Ru反中微子β源部署在一个大型的低背景液体闪烁探测器的中心进行测试。特别是,这种源的紧凑尺寸可以在事件空间分布中产生依赖于能量的振荡模式,这将毫无疑问地确定中微子质量差和混合角。

英文摘要:

Several observed anomalies in neutrino oscillation data can be explained by a hypothetical fourth neutrino separated from the three standard neutrinos by a squared mass difference of a few eV^2. We show that this hypothesis can be tested with a PBq (ten kilocurie scale) 144Ce or 106Ru antineutrino beta-source deployed at the center of a large low background liquid scintillator detector. In particular, the compact size of such a source could yield an energy-dependent oscillating pattern in event spatial distribution that would unabiguously determine neutrino mass differences and mixing angles.
