New MiniBooNE excess interpretation using Pseudo-Hermitian neutrino oscillation

TL;DR

This paper introduces a novel pseudo-Hermitian two-flavor neutrino oscillation model to explain the MiniBooNE excess, showing it fits the data better than standard models by incorporating zero-distance effects and probability asymmetries.

Contribution

It proposes a new pseudo-Hermitian oscillation framework for neutrinos, providing a better data fit than existing models for the MiniBooNE excess.

Findings

Pseudo-Hermitian oscillation explains excess better than standard models.

Zero-distance effect contributes to flavor appearance asymmetry.

Model fits MiniBooNE data more accurately.

Abstract

The excess observed in the MiniBooNE experiment data has been confirmed by several data-releases and analysis. And several attempts to explain such excess are proposed in the litterature using approaches ranging from experimental error to new neutrino theories. None of the attempts seem to fully account for the observed excess. In this paper, we present a new approach this case using a non standard two flavor oscillation theory. In recent years, there is a raising interest in the pseudo-hermitian hamiltonian theories and their impact on several quantum phenomena. The neutrino oscillation is modified using the approach of PT-pseudo hermitian oscillation by having zero-distance effect and asymmetry of the probability of appearance of specific flavors. Such effects can account according to this study for the excess and has a better fit to the data than the best found fit in the standard oscillation framework. We present in this paper the study of the fit of MiniBooNE data the this new oscillation model and its premise.
