摘要：

In this paper we perform for the first time an in-depth analysis of the spectra in the phenomenological supersymmetric Standard Model that simultaneously offer an explanation for the (g - 2)(mu) discrepancy Delta a(mu), result in the right dark-matter relic density Omega(DM)h(2) and are minimally fine-tuned. The resulting spectra may be obtained from [1]. To discuss the experimental exclusion potential for our models, we analyse the resulting LHC phenomenology as well as 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 sigma(SD,p) will probe all of our found solutions.
