Abstract

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 Pαβ ≡ P(να → νβ), and the difference for several accelerator and reactor neutrino experiments. We find that for Pαβ, 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 Pαβ and ΔPαβ 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.

中微子衰变中的马约拉纳CP违反相和NSI效应

在这项工作中，我们研究了存在非标准相互作用（NSI）时中微子衰变的影响，以及马约拉纳相在双味中微子振荡背景下对物质中中微子衰变的影响。我们研究了这些效应对中微子振荡概率 Pαβ ≡ P（να → νβ）的影响，以及几个加速器和反应堆中微子实验的差异。我们发现，对于 Pαβ，马约拉纳相对物质衰变的影响可以通过衰变和 NSI 的同时存在来复制。然而，对 Pαβ 和 ΔPαβ 可观测量的精确测量有可能从衰变和 NSI 的同时存在中分辨出马约拉纳相的影响，从而明确确定马约拉纳相的存在。
