Enhanced violation of Leggett-Garg inequality in three flavour neutrino oscillations via non-standard interactions

Neutrino oscillations occur due to non-zero masses and mixings and most importantly they are believed to maintain quantum coherence even over astrophysical length scales. In the present study, we explore the quantumness of three flavour neutrino oscillations by studying the extent of violation of Leggett-Garg inequalities (LGI) if non-standard interactions (NSI) are taken into account. We report an enhancement in violation of LGI with respect to the standard scenario for appropriate choice of NSI parameters.

Automated summary

In this study, the quantum nature of three-flavor neutrino oscillations was explored by investigating the violation of Leggett-Garg inequalities when non-standard interactions were taken into consideration. The results showed an enhancement in the violation of LGI compared to the standard scenario, with appropriate choice of NSI parameters.
