Cosmic Ray Positron and Electron Excess from Hidden-Fermion Dark Matter Decays

TL;DR

This paper proposes that fermionic dark matter decaying via dimension six operators can explain cosmic ray positron and electron excesses, providing a minimal extension to the standard model that accounts for recent anomalies.

Contribution

It introduces a minimal fermionic dark matter model with decay mechanisms that naturally explain cosmic ray anomalies, expanding the understanding of dark matter properties.

Findings

Dark matter decays via dimension six operators can account for observed anomalies.

The model provides a natural explanation without requiring complex extensions.

Results align with recent cosmic ray experimental data.

Abstract

The anomalies observed in recent cosmic ray experiments seem to strongly constrain the nature of the dark matter. In this letter, we investigate a possibility of the fermionic dark matter with a minimal extension of the standard model. We found that the dark matter decays caused by the dimension six operators can naturally explain the anomalies.
