MSSM dark matter and a light slepton sector: The Incredible Bulk

Understand

Recent experimental results from the LHC have placed strong constraints on the masses of QCD-charged superpartners.

• The MSSM parameter space is also constrained by the measurement of the Higgs boson mass, and the requirement that the relic density of lightest neutralinos be consistent with observations.
• Although large regions of the MSSM parameter space can be excluded by these combined bounds, leptophilic versions of the MSSM can survive these constraints.
• In this paper we consider a scenario in which the requirements of minimal flavor violation, vanishing $CP$-violation, and mass universality are relaxed, specifically focusing on scenarios with light sleptons.
