Singlet extension of the MSSM as a solution to the small cosmological scale anomalies
Singlet extension of the MSSM as a solution to the small cosmological scale anomalies
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 factor can also be obtained). However, we find that the NMSSM (the singlet extension …
