Viability of $\Delta m^2\sim$ 1 eV$^2$ sterile neutrino mixing models in light of MiniBooNE electron neutrino and antineutrino data from the Booster and NuMI beamlines

TL;DR

This study evaluates the viability of sterile neutrino models with a mass-squared difference around 1 eV^2 using recent MiniBooNE, LSND, and other experimental data, including neutrino and antineutrino results from multiple beamlines.

Contribution

It provides a comprehensive global fit analysis of sterile neutrino mixing models incorporating new MiniBooNE data and other experimental constraints.

Findings

MiniBooNE data constrains sterile neutrino models

Antineutrino results impact model viability

Global fits include multiple experimental datasets

Abstract

This paper examines sterile neutrino oscillation models in light of recently published results from the MiniBooNE Experiment. The new MiniBooNE data include the updated neutrino results, including the low energy region, and the first antineutrino results, as well as first results from the off-axis NuMI beam observed in the MiniBooNE detector. These new global fits also include data from LSND, KARMEN, NOMAD, Bugey, CHOOZ, CCFR84, and CDHS. Constraints from atmospheric oscillation data have been imposed.
