Supersymmetric Extension of the Minimal Dark Matter Model

TL;DR

This paper extends the minimal dark matter model with supersymmetry, introducing a super SU(2)L quintuplet where the neutral fermion is the dark matter candidate, and explores its properties and experimental implications.

Contribution

It presents the first supersymmetric extension of the minimal dark matter model with a super SU(2)L quintuplet and analyzes its phenomenological features.

Findings

Dark matter particle mass around 19.7 GeV

Mass splitting due to supersymmetry is negligible

Model explains PAMELA and Fermi-LAT anomalies

Abstract

The minimal dark matter model is given a supersymmetric extension. A super SU(2)L quintuplet is introduced with its fermionic neutral component still being the dark matter, the dark matter particle mass is about 19.7 GeV. Mass splitting among the quintplet due to supersymmetry particles is found to be negligibly small compared to the electroweak corrections. Other properties of this supersymmetry model are studied, it has the solutions to the PAMELA and Fermi-LAT anomaly, the predictions in higher energies need further experimental data to verify.
