Abstract

In this paper we analyze spectra in the phenomenological supersymmetric Standard Model that simultaneously result in the right dark-matter relic density ΩDMh2\Omega_{\rm DM} h^2, offer an explanation for the (g2)μ(g-2)_{\mu} discrepancy Δaμ\Delta a_{\mu} and are minimally fine-tuned. We discuss the LHC phenomenology resulting from these spectra and the sensitivity of dark-matter direct detection experiments to these spectra. We find that the latter type of experiments with sensitivity to the spin-dependent dark-matter-nucleon scattering cross section σSD,p\sigma_{\rm SD,p} will probe all of our found solutions.
