Singlet extension of the MSSM as a solution to the small cosmological scale anomalies
Wang,F; Wang,W; Yang,JM; Zhou,S
In this work we show that the general singlet extension of the minimal supersymmetric standard model (MSSM) can naturally provide a self-interacting singlino dark matter to solve the small cosmological scale anomalies (a large Sommerfeld enhancement facto |
