Dark matter and IceCube neutrinos

TL;DR

This paper proposes that the high-energy neutrino excess observed by IceCube could be explained by decays of dark matter composed of mirror sector baryons, linking neutrino observations to dark matter properties.

Contribution

It introduces a novel dark matter model involving mirror sector baryons decaying into neutrinos, explaining IceCube's high-energy neutrino spectrum features.

Findings

High-energy neutrino excess can be explained by mirror baryon decays.

Tiny mixing between mirror and ordinary neutrinos accounts for spectral features.

Model provides a potential link between dark matter and neutrino observations.

Abstract

We show that the excess of high energy neutrinos observed by the IceCube collaboration at energies above 100 TeV might originate from baryon number violating decays of heavy shadow baryons from mirror sector, which in turn constitute Dark Matter. Due to tiny mixing between mirror and ordinary neutrinos, it is possible to explain the specific features of the IceCube events spectrum.
