Profile likelihood maps of a 15-dimensional MSSM

Understand

We present statistically convergent profile likelihood maps obtained via global fits of a phenomenological Minimal Supersymmetric Standard Model with 15 free parameters (the MSSM-15), based on over 250M points.

• We derive constraints on the model parameters from direct detection limits on dark matter, the Planck relic density measurement and data from accelerator searches.
• We provide a detailed analysis of the rich phenomenology of this model, and determine the SUSY mass spectrum and dark matter properties that are preferred by current experimental constraints.
• We evaluate the impact of the measurement of the anomalous magnetic moment of the muon ($g-2$) on our results, and provide an analysis of scenarios in which the lightest neutralino is a subdominant component of the dark matter.
