Here be Dragons: The Unexplored Continents of the CMSSM
Timothy Cohen, Jay G. Wacker

TL;DR
This paper maps the viable regions of the CMSSM parameter space constrained by Higgs and dark matter data, identifying diverse dark matter mechanisms and predicting experimental signals for future collider and dark matter searches.
Contribution
It provides a comprehensive map of the CMSSM consistent with current measurements, categorizing models by dark matter mechanisms and proposing benchmark points for experimental testing.
Findings
Multiple dark matter mechanisms identified, including well-tempering and coannihilations.
Viable parameter space can be fully explored with current experiments.
Predictions show diverse signals for the 13 TeV LHC and dark matter detectors.
Abstract
The Higgs boson mass and the abundance of dark matter constrain the CMSSM/mSUGRA supersymmetry breaking inputs. A complete map of the CMSSM that is consistent with these two measured quantities is provided. Various "continents," consisting of non-excluded models, can be organized by their dark matter dynamics. The following mechanisms manifest: well-tempering, resonant pseudo-scalar Higgs annihilation, neutralino/stau coannihilations and neutralino/stop coannihilations. Benchmark models are chosen in order to characterize the viable regions. The expected visible signals of each are described, demonstrating a wide range of predictions for the 13 TeV LHC and a high degree of complementarity between dark matter and collider experiments. The parameter space spans a finite volume, which can be probed in its entirety with experiments currently under consideration.
