Description

Indirect detection methods offer a unique way to probe thermal dark matter (DM). Particles at TeV scale, weakly coupled to the Standard Model, face undoubted challenges from decades of null searches; nevertheless the scenario remains compelling, and simple realizations such as Higgsino DM remain largely unexplored. Such scenarios could be finally constrained with gamma-ray observations of the centre of the Milky Way with Imaging Atmospheric Cherenkov Telescopes (IACTs). I will present the results obtained so far from observations of the inner Milky Way halo with H.E.S.S., an array of five IACTs located in Namibia. The results include constraints on model-independent searches as well as on specific SU(2) WIMP scenarios like the Wino, Higgsino and Quintuplet.
