Signatures of Dark Matter in Cosmic-Ray Observations

TL;DR

This paper reviews current indirect dark matter detection efforts through gamma rays, cosmic rays, and neutrinos, discussing reported excesses and their interpretations as potential dark matter signals.

Contribution

It provides a comprehensive overview of recent excesses in cosmic-ray data and discusses the theoretical and analytical approaches used to interpret these as dark matter signatures.

Findings

Reported excesses in gamma-ray and cosmic-ray data analyzed as dark matter hints

Discussion of theoretical models explaining potential dark matter signals

Evaluation of analysis methodologies for indirect dark matter detection

Abstract

I provide a short review of the current status of indirect dark matter searches with gamma rays, charged cosmic rays and neutrinos. For each case I will focus on various excesses reported in the literature which have been interpreted as possible hints of dark matter, and I will use them as examples to discuss theoretical aspects and analysis methodologies.
