Constraining supersymmetry from the satellite experiments

Understand

In this paper we study the detectability of $\gamma$-rays from dark matter annihilation in the subhalos of the Milky Way by the satellite-based experiments, EGRET and GLAST.

• We work in the frame of supersymmetric extension of the standard model and assume the lightest neutralino being the dark matter particles.
• Based on the N-body simulation of the evolution of dark matter subhalos we first calculate the average intensity distribution of this new class of $\gamma$-ray sources by neutralino annihilation.
• It is possible to detect these $\gamma$-ray sources by EGRET and GLAST.
