Dark matter, fine-tuning and $(g-2)_μ$ in the pMSSM
In this paper we analyze spectra in the phenomenological supersymmetric Standard Model that simultaneously result in the right dark-matter relic density $Ω_{\rm DM} h^2$, offer an explanation for the $(g-2)_μ$ discrepancy $Δa_μ$ 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 $σ_{\rm SD,p}$ will probe all of our found solutions.
