Anomalous $U(1{)}^{\prime }$ and Dark Matter

Abstract

We have studied the lightest masses in the fermionic sector of an anomalous $U(1{)}^{\prime }$ extension of the Minimal Supersymmetric Standard Model (MSSM) inspired by brane constructions. The LSP of this model is an XWIMP (extremely weak interaction particle). We have studied its relic density in the cases in which there is mixing with the neutralinos of the MSSM and in the case in which there is not such mixing. We have showed that this extended model can satisfy the WMAP data. To perform this calculation we have modified the DarkSUSY package.
