This article presents the potential of a combined analysis of the JUNO and KM3NeT/ORCA experiments to determine the neutrino mass ordering. This combination is particularly interesting as it significantly boosts the potential of either detector, beyond simply adding their neutrino mass ordering sensitivities, by removing a degeneracy in the determination of $Δm_{31}^2$ between the two experiments when assuming the wrong ordering. The study is based on the latest projected performances for JUNO, and on simulation tools using a full Monte Carlo approach to the KM3NeT/ORCA response with a careful assessment of its energy systematics. From this analysis, a $5σ$ determination of the neutrino mass ordering is expected after 6 years of joint data taking for any value of the oscillation parameters. This sensitivity would be achieved after only 2 years of joint data taking assuming the current global best-fit values for those parameters for normal ordering.
Neutrino Oscillations and Non-standard Interactions with KM3NeT-ORCA
ORCA(Oscillations Research with Cosmics in the Abyss)是位于地中海的下一代水下切伦科夫中微子探测器KM 3 NeT的低能节点。KM 3 NeT-ORCA的主要目标是确定中微子质量排序(NMO)。在几个GeV的能量阈值和几个Mton的有效质量下,KM 3 NeT-ORCA也可以对大气振荡参数进行精确测量。此外,它可以获得广泛的能量和基线,这使得它最适合发现标准模型之外的奇异物理,如中微子的非标准相互作用(NSI)。探测器的中微子质量排序的灵敏度,以及其潜在的确定大气振荡参数。据观察,KM 3 NeT-ORCA将在三年的数据采集后将NSI参数的当前上限提高一个数量级。

Neutrino oscillation tomography of the Earth with KM3NeT-ORCA
KM 3 NeT-ORCA是一个水切伦科夫中微子探测器,设计用于研究大气中微子振荡,主要目标是测量中微子质量有序。穿过地球的大气中微子受到物质效应的影响,改变了它们的味道振荡模式。因此,对ORCA中中微子事件的角度和能量分布的研究可以提供关于地球内部的层析成像信息,这是对标准地球物理学方法的补充。基于探测器响应的完整蒙特卡罗模拟的初步估计表明,经过十年的运行,电子密度可以在地幔中以3-5%的精度测量,在外核中以7-10%的精度测量-取决于质量排序。

A new way to determine the neutrino mass hierarchy at reactors
中微子质量排序的确定目前正在进行的几个实验和建议。一个非常具有挑战性的是它的评价反应堆实验的基础上的微小干扰效应之间的$Δm^2_{31}$和$Δm^2_{32}$振荡。目前的分析需要几年的数据采集和极端的能量分辨率,以实现无论如何小于5 $σ$。参考JUNO的实验条件,我们开发了一种全新的技术,该技术将在不到六年的运行时间内提供稳健的5 $σ$测量。这两种排序可以以允许$Δm^2_{31}$的两个不同值为代价来区分。然而,在相同的分析中,可以以远小于1%的前所未有的精度测量$Δm^2_{31}$上的这种简并度(大约$12\times 10^{-5}$ eV $^2$),即$10^{-5}$ eV $^2$。类比与通常的$χ^2$分析,其中的$Δm^2_{31}$简并是更重要的,进行了讨论。已经进行了系统误差和背景的评估和包含,其中最相关的是增加了两个250 km外的远程反应堆工厂。每个贡献的反应堆堆芯的基线及其空间分辨率已被考虑在内。运行两年后可能的结果和预期的初始减少的可用反应堆功率也进行了研究。这些结果证实了JUNO在确定真空振荡主导区域中的质量有序性方面的非常积极的观点。
