Abstract
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 $\Omega_{\rm DM} h^2$ 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 $\sigma_{\rm SD,p}$ will probe all of our found solutions.
Author comments upon resubmission
1 and 2: We have rewritten lines 222-231. In section 4.4, figure 6, we have included the plot containing data from our previous work and show that the g-2 requirement forbids natural solutions with mDM > 500 GeV, and stressed in the text (line 417-424) that the g-2 requirement is crucial for our results. We also rewrote the last paragraph of our conclusion to clarify the message of our paper (line 445-449).
3 We have included a footnote on page 6 to offer some guidelines to the repository.
