论文摘要
在这项工作中，我们研究了存在非标准相互作用（NSI）的中微子衰变的影响，以及在两种风味中微子振荡的背景下，Majora阶段对中微子衰变的影响。这些效果研究了中微子振荡概率$ p_ {αβ} \ equiv p（ν_α\toν_β）$，以及差异$Δp_{αβ} \ equiv p（ν_α\ toν_β） - p（b bar的barν_α\ toce \ bar的bar bar bar b bar的$barν_β）我们发现，对于$ p_ {αβ} $，可以通过同时存在衰减和NSI来复制Majora阶段对物质衰减的影响。但是，$ p_ {αβ} $和$ΔP_{αβ} $可观察的精确测量可能会明确地识别Majora阶段的存在，通过将其效应从衰减和NSI的并发存在中辨别。
In this work, we investigate the impact of neutrino decay in the presence of Non-Standard Interactions (NSI) along with the effects of the Majorana phase on neutrino decay in matter in the context of two-flavor neutrino oscillations. These effects are studied on neutrino oscillation probabilities $P_{αβ} \equiv P(ν_α \to ν_β)$, and the difference $ΔP_{αβ} \equiv P(ν_α \to ν_β) - P(\bar ν_α \to \barν_β)$ for several accelerator and reactor neutrino experiments. We find that for $P_{αβ}$, the influence of the Majorana phase on decay in matter can be replicated by the simultaneous presence of both decay and NSI. However, precise measurements of the $P_{αβ}$ and $ΔP_{αβ}$ observables have the potential to unequivocally identify the presence of the Majorana phase by discerning its effects from the concurrent presence of both decay and NSI.
