Light neutralinos with large scattering cross sections in the minimal supersymmetric standard model
Light neutralinos with large scattering cross sections in the minimal supersymmetric standard model
Motivated by recent data from CoGeNT and the DAMA annual modulation signal, we discuss collider constraints on the minimal supersymmetric standard model neutralino dark matter with mass in the 5--15 GeV range. The lightest superpartner (LSP) would be a bino with a small Higgsino admixture. Maximization of the dark matter …
