Supersymmetry with Dark Matter is still natural

Understand

We identify the parameter regions of the phenomenological minimal supersymmetric standard model (pMSSM) with the minimal possible fine-tuning.

• We show that the fine-tuning of the pMSSM is not large, nor under pressure by LHC searches.
• Low sbottom, stop and gluino masses turn out to be less relevant for low fine-tuning than commonly assumed.
• We show a link between low fine-tuning and the dark matter relic density.
