大气与太阳振荡振幅的干涉

Interference between the Atmospheric and Solar Oscillation Amplitudes

Patrick Huber, Hisakazu Minakata, Rebekah Pestes

摘要:

我们打算探测中微子振荡的大气尺度波和太阳尺度波之间的干涉效应,这是轻子三代结构的关键结果之一。在真空中,我们表明,有一个自然的和一般的方式分解成这两个振荡模式的振幅。干扰的性质在$\barν_e$消失信道中是最干净的,因为它没有CP相位$δ$。我们发现,即将到来的JUNO实验提供了一个理想的设置来观察这种干扰超过$4\,σ$的意义,即使在保守的假设系统的不确定性。

英文摘要:

We propose to detect the interference effect between the atmospheric-scale and solar-scale waves of neutrino oscillation, one of the key consequences of the three-generation structure of leptons. In vacuum, we show that there is a natural and general way of decomposing the oscillation amplitude into these two oscillation modes. The nature of the interference is cleanest in the $\barν_e$ disappearance channel since it is free from the CP-phase $δ$. We find that the upcoming JUNO experiment offers an ideal setting to observe this interference with more than $4\,σ$ significance, even under conservative assumptions about the systematic uncertainties.
