The Discreet Charm of Higgsino Dark Matter: A Pocket Review

Figure 6

(a) Indirect detection bounds and projections in gamma-ray searches in space and terrestrial telescopes for higgsino DM under CMSSM/mSUGRA boundary conditions. Solid black line shows 90% CL upper bounds on the present-day annihilation cross section to from the statistical combination of Fermi-LAT and MAGIC observations of dSphs [88]; solid magenta line shows the recent bound from 10-year observation of the Galactic Center at HESS [89] under the Einasto profile assumption; solid green line shows the upper bound from antiproton cosmic-ray (CR) data at AMS-02 [90] according to [91] for the NFW profile; and dashed blue line shows the projected reach of CTA 500h under the Einasto profile assumption [53]. (b) In magenta, the current 95% CL upper bound on the annihilation cross section (times velocity) to gamma-ray lines, , from HESS [92] under the Einasto profile assumption, compared to the cross section of our higgsino points.
