Figure 4

Direct detection cross-section limits for spin-independent -nucleon scattering as a function of DM mass . The solid curves are the predictions for WIMPless DM with mediator mass GeV and the Yukawa couplings indicated. The light yellow shaded region is excluded by the experimental results indicated. The dark blue, medium green, medium-dark magenta, and cross-hatched regions are the DAMA-favored regions under different assumptions, see [29] for details. Figure from [29].
