Indirect and direct detection prospect for TeV dark matter in the MSSM-9

Abstract

We investigate the prospects of indirect and direct dark matter searches within the minimal supersymmetric standard model with nine parameters (MSSM-9). These nine parameters include three gaugino masses, Higgs, slepton and squark masses, all treated independently. We perform a Bayesian Monte Carlo scan of the parameter space taking into consideration all available particle physics constraints such as the Higgs mass of 126 GeV, upper limits on the scattering cross-section from direct-detection experiments, and assuming that the MSSM-9 provides all the dark matter abundance through thermal freeze-out mechanism. Within this framework we find two most probable regions for dark matter: 1-TeV higgsino-like and 3-TeV wino-like neutralinos. We discuss prospects for future indirect (in particular the Cherenkov Telescope Array, CTA) and direct detection experiments. We find that for slightly contracted dark matter profiles in our Galaxy, which can be caused by the effects of baryonic infall in the Galactic center, CTA will be able to probe a large fraction of the remaining allowed region in synergy with future direct detection experiments like XENON-1T.
