Description
In this work, we have analysed how neutrino decay is affected in the presence of non-standard interactions (NSI). We also considered the effect of the Majorana phase on neutrino decay in a two-flavor oscillation framework. We have examined scenarios when these sub-leading effects (NSI and decay) can be distinguished. These effects are studied on neutrino oscillation probabilities Pαβ ≡ P(να→νβ), and the difference ΔPαβ ≡ P(να→νβ) − P(ν¯α→ν¯β) for several accelerator and reactor neutrino experiments. Our findings indicate that the impact of the Majorana phase on decay in matter can be mimicked by the combined presence of decay and NSI. However, accurate measurements of Pαβ and ΔPαβ observables have the potential to distinguish these individual sub-leading effects from their simultaneous presence.
