Short-BaseLine Electron Neutrino Disappearance

TL;DR

This paper investigates electron neutrino and antineutrino data from various experiments, revealing a potential CPT-violating asymmetry in their mixing angles, which could imply new physics beyond the standard model.

Contribution

It presents the first analysis suggesting a CPT-violating asymmetry in neutrino and antineutrino mixing angles based on experimental data.

Findings

Hint of CPT-violating asymmetry in mixing angles

Analysis of Gallium and reactor experiment data

Potential implications for neutrino physics

Abstract

We analyzed the electron neutrino data of the Gallium radioactive source experiments and the electron antineutrino data of the reactor Bugey and Chooz experiments in terms of neutrino oscillations. We found a hint of a CPT-violating asymmetry of the effective neutrino and antineutrino mixing angles.
