Review of Neutrino Oscillations With Sterile and Active Neutrinos

TL;DR

This review discusses neutrino oscillation experiments indicating the likely existence of sterile neutrinos alongside active neutrinos, covering models with varying numbers of each and their experimental parameters.

Contribution

It provides a comprehensive overview of neutrino oscillation models involving sterile and active neutrinos, summarizing experimental constraints and parameter spaces.

Findings

Evidence suggests the existence of one or two sterile neutrinos.

Models with multiple sterile and active neutrinos are consistent with current experiments.

Parameters for neutrino oscillations align with recent experimental data.

Abstract

Recently neutrino oscillation experiments have shown that it is very likely that there are one or two sterile neutrinos. In this review neutrino oscillations with one, two, three sterile and three active neutrinos, and parameters that are consistent with experiments, are reviewed.
