# Potential Dark Matter Signals at Neutrino Telescopes

## TL;DR

This paper investigates potential dark matter signals in neutrino telescope data, analyzing combined IceCube and ANTARES observations to identify excesses and angular distributions that could indicate dark matter origins.

## Contribution

It presents a combined analysis of IceCube and ANTARES data, highlighting a low-energy excess and comparing angular distributions to dark matter signal models.

## Key findings

- Detection of a low-energy excess in neutrino data.
- Angular distribution analysis consistent with dark matter signals.
- Enhanced understanding of neutrino flux components.

## Abstract

Recent analyses of the diffuse TeV-PeV neutrino flux highlight a tension between different Ice-Cube data samples that strongly suggests a two-component scenario rather than a single steep power-law flux. Such a tension is further strengthened once the latest ANTARES data are also taken into account. Remarkably, both experiments show an excess in the same energy range (40-200 TeV), whose origin could intriguingly be related to dark matter. In this paper, I discuss the combined analysis of IceCube and ANTARES data, highlighting the presence of the low-energy excess. Moreover, I update the results of the angular analysis for potential dark matter signals, previously obtained with the 4-year High-Energy Starting Events data. In particular, I statistically compare the distribution of the arrival directions of 6-year IceCube events belonging to the low-energy excess with the angular distributions expected in case of different dark matter neutrino signals.
