The minimal two DM components with SUSY

TL;DR

This paper extends the minimal supersymmetric standard model with an additional stable fermion to explain the high-energy positron excess observed by PAMELA, linking it to flipped-SU(5) GUT.

Contribution

It introduces a two-component dark matter model within SUSY that accounts for positron excess, connecting it to grand unified theories.

Findings

Proposes a stable fermion component explaining PAMELA positron data

Integrates dark matter extension with flipped-SU(5) GUT

Suggests new coupling mechanisms in SUSY models

Abstract

We present the dark matter extension of the minimal supersymmetric standard model by one more two component stable fermion N toward explaining the recent rising high energy positron spectrum of the PAMELA data. The needed coupling can arise in the flipped-SU(5) GUT.
