Status of Natural Supersymmetry from the GmSUGRA in Light of the current LHC Run-2 and LUX data

Understand

We study natural supersymmetry in the Generalized Minimal Supergravity (GmSUGRA).

• For the parameter space with low energy electroweak fine-tuning measures less than 50, we are left with only the $Z$-pole, Higgs-pole and Higgsino LSP scenarios for dark matter (DM).
• We perform the focused scans for such parameter space and find that it satisfies various phenomenological constraints and is compatible with the current direct detection bound on neutralino DM reported by the LUX experiment.
• Such parameter space also has solutions with correct DM relic density besides the solutions with DM relic density smaller or larger than 5$\sigma$ WMAP9 bounds.
