# Dark Matter scenarios at IceCube

## TL;DR

This paper explores how decaying Dark Matter particles could contribute to the neutrino flux observed by IceCube, analyzing a two-component model to explain excesses in the data across different energy ranges.

## Contribution

It introduces a two-component neutrino flux model incorporating Dark Matter decay as a novel explanation for IceCube's observed neutrino excesses.

## Key findings

- Dark Matter decay can account for the low-energy excess in IceCube data.
- A two-component model fits the observed neutrino flux better than single-source models.
- The model suggests specific Dark Matter particle properties consistent with observations.

## Abstract

The recent study on the the 6-year up-going muon neutrinos by the IceCube Collaboration and the multi-messenger analyses support the hypothesis of a two-component scenario explaining the diffuse TeV-PeV neutrino flux. Depending on the steepness of the astrophysical power-law, an excess in the IceCube data is shown in the energy range 10-100 TeV (low-energy excess) or at PeV (high-energy excess). In both cases, we characterize a two-component neutrino flux where decaying Dark Matter particles provide a contribution to the IceCube observations.
