Abstract

We assess the extent to which the NMSSM can allow for light dark matter in the 2\gev\lsim \mcnone\lsim 12\gev mass range with correct relic density and large spin-independent direct-detection cross section, \sigsi, in the range suggested by \cogent and DAMA. For standard assumptions regarding nucleon s-quark content and cosmological relic density, ρ, we find that the NMSSM falls short by a factor of about 10 to 15 (3 to 5) without (with) significant violation of the current (g-2)_μ constraints.
