Description
The nearly-pure thermal Higgsino remains one of our best-motivated and least-tested theories of dark matter. The shortest path to discovering such a candidate is likely via observations of TeV-scale gamma rays at the Galactic Center. In this talk I discuss the prospects of current and near future observatories for finding or ruling out Higgsino DM, and how underlying systematics and analysis strategies can affect these prospects. Among the consequences of our study is the finding that H.E.S.S., a leading atmospheric Cherenkov observatory, may have overstated some of their DM limits by close to an order of magnitude. In a future-facing direction, CTA represents substantial potential for a high-signifiance discovery in our future.
