Abstract

Dark matter can be a mixture of axions, axinos and neutralinos in a Peccei-Quinn extension of supergravity. To find out which dark matter candidate is preferred by data we perform a Bayesian statistical analysis on four such scenarios. The main experimental constraints on these models come from the Planck satellite and from the Large Hadron Collider. Weaker constrains arise from other astrophysical, collider and low energy measurements. Our study reveals that the Peccei-Quinn scenario featuring axino dark matter is clearly preferred over the minimal supegravity model with neutralino dark matter.
