Abstract
observations on the annihilation cross section of dark matter particles in the form of Weakly Interacting Massive Particles. The combined 95% C.L. observed upper limits reach hvi 1 10 -23 cm 3 s -1 in the W W -channel and 4 10 -26 cm 3 s -1 in the channels for a dark matter mass of 1.5 TeV. The H.E.S.S. constraints well complement the results from Fermi-LAT, HAWC, MAGIC, and VERITAS and are currently the most stringent in the channels in the multi-GeV/multi-TeV mass range.
