Description
We study a supersymmetric extension of the MSSM that gives both a dark matter (DM) candidate and contributes to account for the 125 GeV Higgs mass. We show how to achieve excellent $\sim$ 10 % fine-tuning and a thermal relic WIMP DM consistent with all existing constraints, by just adding a pair of SU(2) doublets and a singlet to the MSSM. The main annihilation channels in our model are to $t\bar t$ and Higgsinos (the Higgsinos should be light in natural SUSY). We will see how the relic abundance and spin-dependent (SD) direct detection (DD) cross section are related. Therefore imposing the relic density constraint implies a particular value for the SD DD cross section. Fortunately, this value is not ruled out yet, but the next generation of DM experiments should completely rule out or discover this model.
