Sterile neutrinos, dark matter, and resonant effects in ultra high energy regimes

TL;DR

This paper explores how interactions between neutrinos and dark matter could cause resonant effects in neutrino oscillations at ultra high energies, offering new avenues for studying neutrino properties.

Contribution

It introduces the concept that neutrino-dark matter interactions can induce resonant oscillation enhancements at ultra high energies, which can be tested with future data.

Findings

Resonant enhancement of neutrino oscillations due to dark matter interactions.

Potential to probe neutrino properties with ultra high energy neutrino observations.

Implications for dark matter and neutrino physics in astrophysical contexts.

Abstract

Interest in light dark matter candidates has recently increased in the literature; some of these works consider the role of additional neutrinos, either active or sterile. Furthermore, extragalactic neutrinos have been detected with energies higher than have ever been reported before. This opens a new window of opportunities to the study of neutrino properties that were unreachable up to now. We investigate how an interaction potential between neutrinos and dark matter might induce a resonant enhancement in the oscillation probability, an effect that may be tested with future neutrino data.
