abstract = {Dwarf spheroidal galaxies of the Local Group are close
satellites of the Milky Way characterized by a large
mass-to-light ratio and are not expected to be the site of
non-thermal high-energy gamma-ray emission or intense star
formation. Therefore they are amongst the most promising
candidates for indirect dark matter searches. During the
last years the High Energy Stereoscopic System (H.E.S.S.) of
imaging atmospheric Cherenkov telescopes observed five of
these dwarf galaxies for more than 140 hours in total,
searching for TeV gamma-ray emission from annihilation of
dark matter particles. The new results of the deep exposure
of the Sagittarius dwarf spheroidal galaxy, the first
observations of the Coma Berenices and Fornax dwarves and
the re-analysis of two more dwarf spheroidal galaxies
already published by the H.E.S.S. Collaboration, Carina and
Sculptor, are presented. In the absence of a significant
signal new constraints on the annihilation cross-section
applicable to Weakly Interacting Massive Particles (WIMPs)
are derived by combining the observations of the five dwarf
galaxies. The combined exclusion limit depends on the WIMP
mass and the best constraint is reached at 1-2 TeV masses
with a cross-section upper bound of ~3.9x10-24 $cm^3$ s-1 at
a $95\%$ confidence level.},
