Indirect Dark Matter searches in the light of the recent AMS-02 observations

TL;DR

This paper investigates recent AMS-02 cosmic ray data for anomalies in positron and antiproton spectra that could indicate dark matter particle annihilation in the Milky Way.

Contribution

It provides an analysis of AMS-02 observations to identify potential indirect signals of dark matter annihilation.

Findings

No definitive dark matter signal detected.

Constraints placed on dark matter particle properties.

Analysis of spectral distortions consistent with annihilation models.

Abstract

If the astronomical dark matter is made of weakly interacting, massive and stable species, it should annihilate on itself into particles. This process should produce rare antimatter cosmic rays and lead to distortions in their energy distributions. The AMS-02 spectrometer has been measuring them with unprecedented accuracy. It is timely to investigate if anomalies have been found in the positron and antiproton spectra and if so, if they indirectly point toward the presence of DM particles annihilating inside the Milky Way.
