Higgsinos under the microscope

Recent results from higgsino searches by the ATLAS collaboration have made their way into the CERN Courier. The existence of higgsino particles, predicted by theories of supersymmetry, could provide an explanation for the cosmological dark matter. SCIPPers Matthew Gignac, Bruce Schumm, and Giordon Stark contributed to the development of the disappearing track search and the overall combination of results.
